How do you get the cubic feet volume of a ball?

Answer 1

The diameter of a Basketball is about 9.5 inches. Find the volume of air inside

it in cubic centimeters .Neglect the thickness of the ball.(Note:1in=2.54cm)

Step 1. Let D=diameter of basketball, then radius r is D/2 or r=4.75 inches

Step 2. Volume of Sphere is

Step 3.

Answer 2

This only works with a spherical ball, not with, for example, a football.

You'll probably need a calculator.

-- Measure the diameter of the ball ... the fattest part ... in inches.

-- Take half of the diameter; that's the "radius" of the ball.

-- Calculate the "cube" of the radius. That's (radius) times (radius) times (radius).

-- Multiply that answer by 4.1888 .

-- The answer is the volume of the ball, in cubic inches.

-- If you want it in cubic feet, divide the cubic inches by 1,728.

The number you wind up with is the volume of the entire ball, including the skin, so it's a little more than the volume of the air inside. Here are a few benchmarks, just to make sure the answer you get in the "ball" park: 6-inch diameter sphere = 113 cubic inches = 0.065 cubic foot

1-ft diameter sphere = 905 cubic inches = 0.524 cubic foot 2-ft diameter sphere = 7,238 cubic inches = 4.189 cubic feet ======================================== Math :-(

Volume of a sphere with radius ' R ' = 4/3 pi R3 .

4/3 pi = 4.1888 (rounded)

1 cubic foot = 1,728 cubic inches

Answer 3

i have know idea how to find it and i have to for a stupid science project please help!

Answer 4

diameter = 9.3 to 9.5 inches ( 23.622 - 24.130 cms)

Sphere volume = 4/3 * pi * r3

volume = 6911.58 to 7356.49 cubic centimetres

Answer 5

10987658 cubic feet
