<u>Given</u>:
Given that the diameter of the hemisphere is 48 inches.
We need to determine the volume of the hemisphere.
<u>Radius:</u>
The radius of the hemisphere can be determined using the formula,

Substituting d = 48, we get;


Thus, the radius of the hemisphere is 24 inches.
<u>Volume of the hemisphere:</u>
The volume of the hemisphere can be determined using the formula,

Substituting r = 24, we get;



Thus, the volume of the hemisphere is 9216π cubic inches.
Answer:

Step-by-step explanation:
Volume of cone = 90 cm³
Volume of cylinder = ?
<u>Always remember:</u>
Volume of cylinder = 3 × volume of cone
Volume of cylinder = 3 × 90
Volume of cylinder = 270 cm³
