Answer:

Correct answer: V = 3,888 π in³

Explanation:

Given:

Radius of the sphere r = 18 in

The volume of the hemisphere is:

V = (2/3) · r³· π

V = (2/3) · 18³ · π = (2/3) · 5,832 · π = 3,888 π in³

V = 3,888 π in³

Answer:

Volume (V) = 3888π cubic inches

Explanation:

The volume of the drawn hemisphere is expressed as:

V = 2/3 π r ^3

Parameters given:

r = 18 inches

r = r ^ 3

= 18^3

= 18 * 18 * 18

r = 5832 inches

Therefore:

Volume (V) = 2/3 * π * 5832

V = 2/3 * 5832 π

V = 2 * 1944π

V = 3888 π cubic inches

Maths is fun!
