I dont understand the last bit....is that exactly how the question reads?

A gardener is installing a circular garden. The circumference of the circle 132 feet. What radius should he use to layout the circle if he uses = $\pi 22/7$ The radius is_______feet.

3. ChmE

so 132 = pi 22/7

4. ChmE

132 = 2 pi r

5. ChmE

2 pi r = pi 22/7

6. ChmE

solve for r

7. Claire4christ

im confuse sorry

8. CalebBeavers

When you solve for r you get 1.57

9. Claire4christ

what formula do i have to use??

10. nphuongsun93

@ChmE how is 132 = pi 22/7? what does layout mean and the pi 22/7 suppose to be?

11. Claire4christ

3.14

12. nphuongsun93

i see. i will assume the question gives the circumference and asks for the radius. the circumference equation = 2r pi 132 = 2r pi (pi = 3.14) can you solve for r?

13. Claire4christ

132=2xrx3.14??
