The area of a circle is 28.26 what is the diameter?

Answer 1

Remember the circle equations.

A = pi r^2

C = 2 pi r = pi d ( Hence d = 2r)

Algebraically rarranging

r = sqrt(A/pi)

2r = d = 2(sqrt(A/pi))

Hence

d = 2(sqrt(28.26 / 3.141592...))

d = 2(sqrt(8.99543....)

d = 2(2.999239...)

d = 5.99847.... ~ 6 The answer!!!!!

Answer 2

6

Answer 3

its not 6
