Question

Calculate the volume of the cone with the hemisphere scooped out of the base. Note: 20 cm is the slant height

Answer 1

1496.59125cm round to whatever you need

Answer 2

3418.02 cm²

Explanation:

Volume :

Volume (cone) - Volume (hemisphere)

1/3πr²h - 2/3πr³

1/3 x π × 64 x (√20² - 8²) - 2/3 x π x (4)³

64π/3 (√336 - 2 x 2/3)

64π (18.33 - 1.33)

64π × 17

201.06 x 17

3418.02 cm²
