Find the area and the circumference of a circle with radius 9 ft.
Use the value 3.14 for pie, and do not round your answers. Be sure to include the correct units in your answers.
Answers:
Area = 254.34 square feet
Circumference = 56.52 feet
=========================================================
Work Shown:
Area = pi*(radius)^2
A = pi*r^2
A = 3.14*9^2
A = 254.34 square feet
----------------
Circumference = 2*pi*(radius)
C = 2*pi*r
C = 2*3.14*9
C = 56.52 feet
The two results are approximate since pi = 3.14 is approximate.
1st area of circle:
[tex]\bold{\ area \ of \ circle \ : \pi r^2}[/tex]
[tex]\hookrightarrow \sf (3.14)(9)^2[/tex]
[tex]\hookrightarrow \sf 254.34 \ ft^2[/tex]
2nd circumference of circle:
[tex]\bold{circumference \ of \ circle \ : \ 2\pi r}[/tex]
[tex]\hookrightarrow \sf 2(3.14)(9)[/tex]
[tex]\hookrightarrow \sf 56.52 \ ft[/tex]
area of circle = 254.34 ft²circumference of a circle = 56.52 ftKevin and Randy Muise have a jar containing 63 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $7.35. How many of each type of coin do they have?

Find the value of cos F rounded to the nearest hundredth, if necessary
Using the trigonometric ratios, the value of cos F in the right angle triangle is 0.28 .
What are right angle triangle?Right angle triangle are triangle that has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore,
cos F = adjacent / hypotenuse
adjacent = FE
hypotenuse = 50
50² - 48² = FE²
FE = √2500 - 2304
FE = √196
FE = 14
Therefore,
cos F = 14 / 50
cos F = 0.28

Answer:
162
Step-by-step explanation:
to find the surface area of the rectangles do base x height
5 x 10 = 50
there are 3 sides on a triangle so do 50 x 3 = 150
now we need to find the area of the triangles
the formula for the surface area would be base x height ÷ 2
3 x 4 = 12
12 ÷ 2 is 6
because there are 2 triangles you would need to multiply it by 2
6 x 2 is 12
add it all together
12 + 150 is 162

If you were to roll two dice, what is the probability that the sum of the numbers showed on the dice is greater than 5?
The probability that an outcome is greater than 5 is the likelihood of the outcome
The probability that the sum of the numbers showed on the dice is greater than 5 is 13/18
How to determine the probability?The sample size of a roll of two dice is:
n(S) = 36
The number of outcomes that have a sum greater than 5 is:
Greater than 5 = 26
So, the required probability is:
P = 26/36

the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = 10 , h = v and A = 50 , then

a simple random sample of earthquake depths yields the following:
n=600, x=5.82 km, and s=4.93 km
use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 5.00km
The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region.
Test-Static tData;
mean = 5.82s = 4.93n = 600Let's calculate the t-value
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } }[/tex]
Substitute the values into the equation and solve;
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } } \\t = \frac{5.82 - 5}{\frac{4.93}{\sqrt{600} }} \\t = \frac{0.82}{0.201} \\t = 4.079[/tex]
The t-value is 4.079
The allowed significance value = 0.01
The degree of freedom is n -1, which becomes 600 - 1 = 599.
