# Find the Surface Area cone (8cm)(5cm) h=8cmr=5cm
The surface area of a cone is equal to the area of the base plus the area of the cone.
Substitute the values of the length r=5 and height h=8 into the formula. Pi π is approximately equal to 3.14.
(π⋅5)(5+(5)2+(8)2)
Move 5 to the left of π.
5⋅π(5+(5)2+(8)2)
Simplify each term.
Raise 5 to the power of 2.
5π(5+25+(8)2)
