Question

The radius, R, of a sphere, is 6.3cm. Calculate the sphere's volume, V.

Use the value 3.14 for
`\pi`, and round your answer to the nearest tenth. (Do not round any intermediate computations.)

Answer 1

1046.9

Explanation:

The formula for calculating volume of a sphere is the following:

4/3·π·r³

The question asks for you to substitute 3.14 instead of using the exact number π.

∴V=4/3·3.14·6.3^3

V=1046.86344

Now round your answer to the nearest tenth:

1046.86344 -->1046.9

∴V=1046.9
