How do you find the radius of a circle so that its area ans circumference have the same value?
The radius would have to equal 2 2*pi*r=pi*r^2 2*pi*2=pi*2^2 4pi=4pi
Technically they cannot have the same value as circumference is a one-dimensional unit and area is a two-dimensional unit. inches cannot equate to square inches. Now if you are just curious as to unrelated magnitude then: A=πr^2 and C=2πr If A=C πr^2=2πr r=2
