Question

how would i find the area of a circle with a diameter of 8

Answer 1

Pi4^2

Answer 2

You use the equation Area = \[\pi * r ^{2}\]

Answer 3

wouldnt it be (pi/4)X(diameter)^2

Answer 4

area of a circle = pi * r^2
r = 1/2 of d.....so if d is 8, then r = 4

A = pi * 4^2
A = pi * 16

Answer 5

So the radius is always half of the diameter, therefore,
Area would be pi times 16 because 4 squared is 16!

Answer 6

oh ok
