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

Answer:
3418.02 cm²
Step-by-step 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
