The volume of the cup whose height is 8.3 cm and radius is 2.37 cm in cubic centimeters, by rounding off nearest tenth is 146.4 [tex]cm^{3}[/tex].
Volume of cup by rounding off nearest tenth = 146.4 [tex]cm^{3}[/tex].
What is volume of Cylinder?
The volume V of a cylinder with radius r is the area of the base B times the height h .
V=Bh or V=π[tex]r^{2}[/tex]h
It is given that,
height= 8.3 cm
Circumference = 14.9 cm
By using the circumference we first find the radius of circular base or top,
Circumference of the circle = 2πr
14.9= 2 x 3.14 x r
14.9= 6.28 x r
r= [tex]\frac{14.9}{6.28}[/tex]
r= 2.37 cm
Hence, the radius of the circle is 2.37 cm.
Volume of cup( cylindrical shape ) = π[tex]r^{2}[/tex]h
= 3.14 x 2.37 x 2.37 x 8.3
= 26.062 x 5.616
= 146.364 [tex]cm^{3}[/tex]
= 146.4 [tex]cm^{3}[/tex] (nearest tenth)
The volume of the cup in cubic centimeters, by rounding off nearest tenth is 146.4 [tex]cm^{3}[/tex].

An auditorium has rows of seats with a seats in each row Kayla
knows there are at least 70 seats but fewer than 156 seats in the
auditorium. How many rows of seats can there be in the auditorium
Use Exercises 1-a to answer the question
1. Explain how you would find the least possible number of rowe
in the auditorium
2. How would you find all the possible numbers of rows, without
having to check if & is a factor of every number between
70 and 1507
3. Name all the possible numbers of rows in the auditorium,
Step-by-step explanation:
Note: there is a typo, 'a' should be '8'The number of seats in each row is 8 and the total number of seats is between 70 and 150.
Let x be the number of rows, then we have the inequality:
70 ≤ 8x < 156Divide all sides by 8 to get:
70/8 ≤ x < 156/89 ≤ x ≤ 19 (taking closest integers)So the number of rows is between 9 and 19 both inclusive.
All possible number of rows
9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19Answer:
1. 9 rows
2. see below
3. 9, 10, 11, 12, 13, 14, 15, 16, 17, 18
Step-by-step explanation:
Please note that I believe there are typing errors in the question and that the given information should be:
8 seats in each rowAt least 70 seatsLess than 150 seatsQuestion 1
To determine the least possible number of rows in the auditorium, divide the least number of seats by the number of seats in a row:
⇒ 70 ÷ 8 = 8.75
As the answer is a decimal, round it up to the nearest whole number.
Therefore, the least possible number of rows in the auditorium is 9 rows.
Question 2
Find the greatest number of rows by dividing the greatest number of seats by the number of seats in a row:
⇒ 150 ÷ 8 = 18.75
As there should be fewer than 150 seats we cannot round the number up (as this would make there be more than 150 seats), so instead must round it down to 18.
Therefore, the greatest number of rows in the auditorium is 18 rows.
Question 3
As we have found the least number of rows in question 1 and the greatest number of rows in question 2, all we need to do is list all the numbers between (and including) these numbers.
Therefore, all the possible numbers of rows in the auditorium are:
9, 10, 11, 12, 13, 14, 15, 16, 17, 18

The prism below has dimensions 2 inches by 3 inches by 4 inches. To the right of the prism, shade the number of prisms necessary, if stacked on top of each other as shown, to create a new prism with a surface area between 100 square inches and 130 square inches.
HELPPPPPPPPPPPP
The area of the stacked prism is the amount of space on it
To create a total area between 100 square inches and 130 square inches, 2 to 2.5 prisms
How to determine the number of prisms?
The dimension of the prism is given as:
2 inches by 3 inches by 4 inches
The surface area of the prism is calculated as:
A = 2 * (LW + WH + LH)
This gives
A = 2 * (2 * 3 + 3 * 4 + 2 * 4)
Evaluate the product
A = 52
When the prisims are stacked onto one another, the surface area is between 100 square inches and 130 square inches.
So, the number of prisms (n) needed is:
100/ 52 < n < 130/52
Evaluate the quotient
1.9 < n < 2.5
Approximate
2 < n < 2.5
Hence, 2 to 2.5 prisms are needed to create a total area between 100 square inches and 130 square inches.

Rectangular pyramid B is the image of rectangular pyramid A after dilation by a scale factor of 33. If the surface area of rectangular pyramid B is 1215 cm^2
2
, find the surface area of rectangular pyramid A, the preimage.
After dilation by a scale factor of 33, the surface area of rectangular pyramid A, the preimage is 1.12 cm²
To find the area of rectangular pyramid A given rectangular pyramid B, we need to know its scale factor.
What is scale factor?Scale factor is the ratio of the corresponding sides of two objects.
Now, since rectangular pyramid B is the image of rectangular pyramid A, we have that (since we are dealing with areas)
(Scale factor)² = surface area of rectangular pyramid B/surface area of rectangular pyramid A
Surface area of rectangular pyramid ASo, surface area of rectangular pyramid A = surface are of rectangular pyramid B/(scale factor)²
Since
scale factor = 33 and surface area of rectangular pyramid B = 1215 cm²surface area of rectangular pyramid A = surface area of rectangular pyramid B/(scale factor)²
So, substituting the values of the variables into the equation, we have
surface area of rectangular pyramid A = 1215 cm²/33²
= 1215 cm²/1089
= 1.12 cm²
So, after dilation by a scale factor of 33, the surface area of rectangular pyramid A, the preimage is 1.12 cm²
