Question

The surface area of a cone is 396π square inches. If the radius is 12 inches, find the slant height of the cone.

Answer 1

Answer:

Slant height = 33 inches

Step-by-step explanation:

r = 12 inches

Lateral Surface Area of cone = 396π square inches

πrl = 396π

π * 12 * l = 396π

$l=\frac{396\pi }{12*\pi }$

l = 33 inches
