The base of a cone is a circle.

The area of a circle is $\pi r^2$ .

Thus, the area of the base of a cone $\pi r^2$ .

The derivation of the formula for the area of a circle involves a bit of calculus, but if you'd like, I can walk you through it.

16 feet perimeter 5 feet long what is the width

miskamm [114]

P=2L+2W
L=Length
W=Width
P=Perimeter=16
So you have:
16=2×5+2w
Multiply 2 and 5 and get:
16=10+2w
Subtract 10 from both sides and get:
6=2w
Divide by 2 and get:
3=W
The width is 3.
