Question

What is the volume of a hemisphere with a diameter of 8ft, rounded to the nearest tenth of a cubic foot

Answer 1

Answer:

The volume of the hemisphere is $1071.78\ ft^3$.

Step-by-step explanation:

We have,

The diameter of a hemisphere is 8 ft. It is required to find its volume.

The formula of the volume of hemisphere is given by :

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

r is radius of hemisphere

Here, r = 4 ft

So,

$V=\dfrac{2}{3}\times 3.14\times (8)^3\\\\V=1071.78\ ft^3$

So, the volume of the hemisphere is $1071.78\ ft^3$.
