How many cubic inches of material do you need to make a solid rubber ball with a diameter of 3 inches?

Answer 1

Volume of a sphere = 4/3 (pi) (radius)3

Radius = 1/2 diameter

Volume of a 3-inch-diameter ball = 4/3 (pi) (1.5)3 = 4.5 (pi) cubic inches

You should have no trouble taking care of the (pi) factor and rounding the

result any way you want it.

Answer 2

To calculate the volume of a sphere, you can use the formula V = (4/3) * π * r^3, where r is the radius of the sphere. Given a diameter of 3 inches, the radius is 1.5 inches. Plugging this value into the formula, you find that the volume of the solid rubber ball is approximately 14.14 cubic inches.

Answer 3

volume of sphere (ball) is 4/3 x pi x r^3

(r=diam /2)

so 4/3 x3.14 x1.5^3

Answer 4

The volume of a sphere is 4/3. Multiply that times pi and then by r3. You will need 14 cubic inches of material to make a ball with a 3 inch diameter.
