Answer 3

Lets say the radius is 2. Lets try it. The formula is\[\frac{ 1 }{ 3 }Bh\]

Answer 4

1/3*2*h ?

Answer 5

no B stands for area of base

Answer 6

so it would be 1/3*12.57*4 (lets say the height is 4)

Answer 7

Thats for the first one ^ what do you think you'll get?

Answer 8

1/3*50.27*4 (for the second one)
