Question

The volume of a hemisphere is 155232 cm³. What is the radius of the hemisphere?

• A. 40 cm
• B. 42 cm
• C. 38 cm
• D. 36 cm

Answer 1

Answer:

B. 42 cm

Solution:

Given:

Volume of a hemisphere is 155232 cm³

Formula Used:

Volume of Hemisphere = 2π/3 × r³

Calculation:

2π/3 × r³ = 155232

⇒ π × r³ = 232848

⇒ 22/7 × r³ = 232848

⇒ r³ = 74088

⇒ r = 42 cm
