<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,
where r is the radius of the hemisphere.
Substituting r = 9.8 in the above formula, we get;
Simplifying, we get;
Rounding off to the nearest tenth, we get;
Thus, the volume of the hemisphere is 1970.2 cubic inches.
Step-by-step explanation:
Before we answer, the area of a Circle given it radius is
The area of a circle given it diameter is
So let answers question 1-4.
1. The area is
2. The area is
3.
4.
For the 5th problem, circumference is
where d is the diameter and
where r is the radius.
A circumference of 100 m means the radius is 50 because
So this means the area is
