Answer:
0.143059
Step-by-step explanation:
Answer:
The diameter of the pizza = 14 in
Radius of the pizza = (14/2)in = 7in
Area of a whole pizza =
πr^2
=( 22/7 × 7^2)in^2
=( 22/7 × 49)in^2
154 in^2
Area of a half pie =( 1/2 × 154)in^2 = 77in^2
Area of one of 8 slices = (1/8 × 154)in^2 = 19.25in^2

So the equation for the volume of the sphere is
.
For this, you'll need to plug in 128 pi into the volume placeholder and solve for r.
Firstly, divide by pi on each side of the equation to cancel out pi. Your equation will look like this:
Next, you'll want to multiply 3/4 on each side to cancel out 4/3. Your equation will look like this:
Lastly, you'll want to 3rd root each side of the equation, and your answer should be
.
The correct option is B. 4.58
