Question

EO GEOMETRYVolume of a sphereThe diameter, D, of a sphere is 19.8 m. Calculate the sphere's volume, V.Use the value 3.14 for it, and round your answer to the nearest tenth. (Do not round any intermediate computations.

Answer 1

Remember that

The volume of a sphere is equal to

`V=(4)/(3)\cdot\pi\cdot r^3`

we have

r=19.8/2=9.9 m -----> the radius is half the diameter

pi=3.14

substitute given values

`V=(4)/(3)\cdot3.14\cdot9.9^3`

V=4,062.3 m3
