Acone has a radius of 4 units and a height of 6 units.
its volume is a.96 b.100.48 c. 301.44 d.401.92 cubic units.
if a cylinder has the same radius and the same height as the cone, then its volume is a.66.99 b288 c.301.44 d.904.32 cubic units.

B is correct

C is correct

Step-by-step explanation:

A cone has a radius of 4 units and a height of 6 units.

Formula:

Where, r=4 and h=6

If a cylinder has the same radius and the same height as the cone.

Formula:

Where, r=4 and h=6

it is 10.6 according to my calculations

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
