Question

A toy is in the form of a cone mounted on a hemisphere and a cylinder. The radius and height of the cone are 3 m and 4 m. Find the volume of the given solid?

• A. 207.30 m³
• B. 150.79 m³
• C. 188.50 m³
• D. 120.58 m³

Answer 1

Answer:

A. 207.30 m³

Volume of the toy = volume of the cone + volume of the hemisphere + volume of the cylinder = 1/3πr²h + 23πr³ + πr²h = (13 × 3.14 × 32 × 4) + (2/3 × 3.14 × 33) + (3.14 × 32 × 4) = 207.30 m³
