In a house, there is a small statue in the shape of a cylinder. The cylinder has a diameter of 8 inches and a height of h inches
Which equation can be used to find V, the volume of the cylinder in cubic inches?
The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.
What is a cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi.
Given that;
Diameter d = 8inRadius r = d/2 = 8in/2 = 4inHeight = hVolume of the cylinder V = ?V = π × r² × h
V = π × (4)² × h
V = π4²h
Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

Answer:
Perimeter = 132.2 ft
Area = 766.9 ft^2
Step-by-step explanation:
Perimeter of Circle : P = 2 * pi * r
Perimeter of Rectangle : P = 2*l + 2*w
Perimeter of Circle : P = 2 * pi * 15 = 30*pi ft
Perimeter of Rectangle : P = 2*15 + 2*4 = 30 + 8 = 38 ft
Total Perimeter = 132.2 ft
Area of Circle : A = pi * r^2
Area of Rectangle = L * W
Area of Circle : A = pi * 15^2 = 225*pi ft^2
Area of Rectangle = 15 * 4 = 60 ft^2
Total Area = 225*pi + 60 = 766.9 ft^2
Answer:

So basically there are the letters V, U , T, and S on each corner right? If you remove the X and cross in the middle, the shape of V, U, T, and S gives you a parallelogram. A parallelogram is a shape that has two pairs of parallel sides. The lines V and U are parallel to the lines S and T. The same goes for lines V and S; they are parallel to U and T.

Here are the steps to solve for x:
3(x+4) + 2 = 2+5(x-4)
1. Distribute to get rid of the parentheses
3x+12+2 = 2+5x-20
2. Combine like terms
3x+14 = 5x -18
3. Get like terms on the same side
3x+14 = 5x -18
-14 -14
3x = 5x -32
-5 -5
-2x = -32

suppose you throw a ball straight up from the ground with a velocity of 224 feet per second. as the ball moves up, gravity slows it. eventually, the ball begins to fall back to the ground. the height h of thr ball after t seconds in the air is given by the equation h=-16t^2 + 224t. use the given information to answer.
a. find the height of the ball after four seconds. (type a whole number)
b. how long will it take the ball to reach a height of 768 ft?
c. how long after you throw the ball will it return to the ground? (type w whole number)
a. The height of the ball after four seconds is 640 ft
b. The time the ball reachs a height of 768 ft is 6 s or 8 s.
c. The time the ball reachs the ground after it is thrown is 14 seconds.
Since the height of the ball is a parabola, we need to know the equation parabola is
What is a parabola?A parabola is an equation of the form x(t) = at² + bt + c
a. Height of the ball after four secondsThe height of the ball after four seconds is 640 ft
Since the height of the ball is represented by the equation h(t) = -16t² + 224t. The height of the ball after four seconds is when t = 4.
So, h(t) = -16t² + 224t.
h(4) = -16(4)² + 224(4)
h(4) = -16(16) + 224(4)
h(4) = -256 + 896
h(4) = 640 ft
The height of the ball after four seconds is 640 ft
b. How long will it take the ball to reach a height of 768 ft?The time it takes the ball to reach a height of 768 ft is 6 s or 8 s.
To find this time, we substituie h = 768 into the equation for the height of the ball.
So, h(t) = -16t² + 224t
768 = -16t² + 224t.
16t² - 224t + 768 = 0
t² - 14t + 48 = 0
Using the quadratic formula, we find t
[tex]t = \frac{-(-14) +/- \sqrt{(-14)^{2} - 4 X 1 X 48} }{2 X 1} \\t = \frac{14 +/- \sqrt{196 - 192} }{2}\\t = \frac{14 +/- \sqrt{4} }{2}\\t = \frac{14 +/- 2 }{2}\\t = \frac{14 + 2 }{2} or t = \frac{14 - 2 }{2}\\t = \frac{16}{2} or t = \frac{12}{2}\\t = 8 or 6[/tex]
So, the time it takes the ball to reach a height of 768 ft is 6 s or 8 s.
c. How long after you throw the ball will it return to the ground?The time it takes the ball to reach the ground after it is thrown is 14 seconds.
To find the time it takes the ball to reach the ground, the height, h = 0.
So, h(t) = 0
-16t² + 224t = 0
-16t(t - 14) = 0
t(t - 14) = 0
t = 0 or t - 14 = 0
t = 0 or t = 14 s
So, the time it takes the ball to reach the ground after it is thrown is 14 seconds.

For Tom:
£83 * 2 = £166
For Ben:
£83 * 7 = £581
Checking our work:
Since the decimals are the same, this means the ratios are equal.
2/7 = 0.2857
