What is the volume of a cone with a radius of 4 and a height of 15?
a 251.33 units
b 753.98 units
c 900 units
d 39.79 units

A. 251.33 cubic units

Step-by-step explanation:

volume of cone = (1/3) * area of base * height

Since your base is a circle, the area of the base is pi * r^2.

Now we have

volume of cone = (1/3) * pi * r^2 * h

volume of cone = (1/3) * 3.14159 * 4^2 * 15

volume of cone = 251.33 cubic units

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
