If the volume of a hemisphere is 92160 pie cubic cm then find<br>its radius.

My name is Ann [436]

Answer:

radius = 51.70 cm

Step-by-step explanation:

Volume = (2/3) π r³

Volume = 92160 π

Radius = ?

Using the above formula

V = (2/3) π r³

r³ = v/((2/3) π)

r³ = ((92160 π) x 3) / (2 x π)

r³ = 276480/2 because (π/π) = 1

r³ = 138240

Taking cube root on both sides

r = 51.70 cm
