Answer:

The volume of the hemisphere = 496741.6 m³

Explanation:

Volume of a sphere is= (4/3) × π × r³

r is the radius

π is 22/7

hemisphere is half of an sphere,

so the volume of henisphere is (2/3) × π × r³

Given that ;

r = 61.9 m


V = (2\pi (61.9)^(3))/(3) = 496741.6

therefore, the volume of the hemisphere is 496741.6 m³

Answer:

The volume of the hemisphere is 496741.6 m³

Explanation:

The volume of an sphere is given by:


V_(s) = (4\pi r^(3))/(3)

In which
\pi = 3.14 and r is the radius.

An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So


V_(h) = (V_(s))/(2) = (2\pi r^(3))/(3)

In this question:


r = 61.9. So


V_(h) = (2\pi (61.9)^(3))/(3) = 496741.6

The volume of the hemisphere is 496741.6 m³
