Question

Esther and Jim plan to retricea pond to their property. The area of the pond is 44 square meters.
What is the radius?
Remember, a=3.14r^2
*Use 3.14=22/7

Answer 1

44=(22/7)r^2 solve for r

Answer 2

so... r^2 = 44/(22/7)

Answer 3

r^2=308/22

Answer 4

r= sqrt(308/22)

Answer 5

Thats the answer.

Answer 6

Thanks!

Answer 7

You will need to work backwards to solve this question since you already know the answer (area) is 44 square meters.

44 = (22/7) * r^2

If you multiply both sides by 7/22, you will get rid of the fraction over on the right side of the equation.

(7/22) * 44 = (7/22) * (22/7) * r^2

14 = r^2

so, r = sqrt(14)

Answer 8

how do you retricea pond?
