Answer:
V = 140 pi ft^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 Bh where B is the area of the base
V = 1/3 (35 pi) * 12
V = 4*35 pi
V = 140 pi ft^3
We cannot approximate pi if we want the exact answer
Answer:
16
Step-by-step explanation:
Hi.
This is just messing around with exterior angles.
I say around 120 degrees, if I forgot what exterior angles were.
But <em>with quick calculation, it is probably 120 degrees</em>
