What is the surface area of the cone? (Use 3.14 for Pi and round to the nearest hundredth.) A cone with diameter 8 feet, slant height 12.6 feet, and height 12 feet. S A = pi r l + pi r squared 41.2 pi feet squared 66.4 pi feet squared 111.6 pi feet squared 164.8 pi feet squared

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
