(2.07)Solve for pi: C = 2pir.

pi equals 2 times C over r
pi equals C over quantity 2 times r
pi equals C over r
pi equals r times C over 2

Answer 1

To solve for Pi do the following:

C = 2Pi • r
C/2r = Pi

The solution would be Pi equals C over quantity 2 times r.

Answer 2

Given circumference formula for circle C = 2pir.

The question is asking to solve for pi or make pi as the subject.

With pi we have 2 r multiplied.We always perform the opposite operation both sides.Opposite of multiplication is division so we divide both sides by 2r

Dividing both sides by 2r we have:

$\frac{c}{2r} =pi(\pi )$

Among all the options pi equals C over quantity 2 times r is the right answer.
