Question

What is the volume of a hemisphere with a radius of 3.8in, rounded to the nearest tenth of a cubic inch

Answer 1

Answer: $114.9\ in.^3$

Step-by-step explanation:

Given

The radius of the hemisphere is $r=3.8\ in.$

The volume of a hemisphere is given by

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

Insert the value

$V=\dfrac{2}{3}\pi \times (3.8)^3\\\\V=114.9\ in.^3$
