What is the volume of a hemisphere with a radius of 9.8in, rounded to the nearest tenth of a cubic inch?

Fofino [41]

<u>Given</u>:

Given that the radius of the hemisphere is 9.8 inches.

We need to determine the volume of the hemisphere.

<u>Volume of the hemisphere:</u>

The volume of the hemisphere can be determined using the formula,

$V=\frac{2}{3} \pi r^3$

where r is the radius of the hemisphere.

Substituting r = 9.8 in the above formula, we get;

$V=\frac{2}{3} (3.14)(9.8)^3$

Simplifying, we get;

$V=\frac{2}{3} (3.14)(941.192)$

$V=\frac{5910.69}{3}$

$V=1970.23$

Rounding off to the nearest tenth, we get;

$V=1970.2 \ in^3$

Thus, the volume of the hemisphere is 1970.2 cubic inches.
