Answer 1

1231.5 units^2

Explanation:

The formula for volume of a cone is

V = 1/3πr^2, where

• V is the volume in cubic units
• r is the radius (find using circular base)
• and h is the height (line extending from the top of the cone to the circular base)

We see from the diagram that the height is 24 cm and the radius is 7 cm. Now, we can plug these values in for h and r respectively in the volume formula:

V = 1/3π(7)^2(24)

V = 1/3π(49)(24)

V = 1/3π*1176

V = 392π

V = 1231.50432

V = 1231.5 cm^3
