Question

The radius, R, of a sphere is 8.4 cm. Calculate the spheres volume, V. Use the value 3.14 for n, and round your answer to the nearest tenth. ( do not round any intermediate computations.)

Answer 1

Given:

it is given that the radius of the sphere is 8.4 cm

Find:

we have to find the volume of the sphere.

Explanation:

The volume of a sphere with radius r is

$V=\frac{4}{3}\pi r^3$

given radius r = 8.4 cm

Therefore, the volume of the given sphere is

$\begin{gathered} V=\frac{4}{3}\times\pi\times(8.4)^3 \\ V=\frac{4}{3}\times(3.14)\times(592.704) \\ V=2481.5\text{ }cm^3 \end{gathered}$

Therefore, the volume of the given Sphere is 2481.5 cm^3
