Question

The radius of the sphere is 10 units. What is the approximate volume of the sphere? Use and round to the nearest whole cubic unit. 42 cubic units 126 cubic units 4187 cubic units 73,385 cubic units

Answer 1

Option C.

Explanation:

Radius of the sphere is given as 10 units.

We have to calculate the volume of this sphere.

Since formula to measure the volume of sphere is V =
`(4)/(3)\pi r^(3)`

V =
`(4)/(3)\pi 10^(3)`

=
`(4)/(3)(3.14)(10^(3))`

= 4186.67

≈ 4187 cubic units.

Option C. is the answer.

Answer 2

The approximate volume of the sphere= 4187 cubic units

Explanation:

Points to remember

Volume of sphere = (4/3)πr³

Where 'r' radius of sphere

To find the volume of sphere

It is given that the radius of the sphere is 10 units. ,

Here radius r = 10 units

Volume = (4/3)πr³

= (4/3) * 3.14 * 10³

= (4/3) * 3140

= 4186.666 ≈ 4187 cubic units
