Question

The formula for the volume of a cone is V= 1/3pir^2h where V represents the volume, r represents the radius of the base, h represents the height. What is the height of a cone with a volume of 66 cubic centimeters and a base with a radius of 3 centimeters?

Answer 1

Answer:

H = 7cm

Step-by-step explanation:

Volume of a cone = V = ⅓πr²h

H = ?

R = 3cm

V = 66cm³

π = 3.14

V = ⅓ * π * r² * h

66 = ⅓ × 3.14 × 3² × h

66 = ⅓ * 28.26h

3 * 66 = 28.26h

198 = 28.26h

H = 198 / 28.26

H = 7cm

The height of the cone is 7cm
