A right come has a slant height of 6 and a radius of 4 what is the surface area?

The SA formula to find a right cone is area of the base x 1/2 (perimeter) (slant height)

To find the area of the base you do radius squared x pi

Radius=11

So 121pi is area of the base

Perimeter=circumference of the circle

So perimeter=24pi

So 121pi x 1/2 (12pi) (6)

12 x 6=72pi/2=36pi

121pi x 36pi = 4356pi

Answer: 4356pi
