The pond is circular, so we can apply circle formulas. In this case, we can use the circumference of a circle formula and input the corresponding variable in and solve for the diameter.
Circumference of a circle formula:
C=2πr, where C=circumference and 2r=diameter
We can rearrange the formula using the commutative property of multiplication to get 2r, which 2r=diameter (d):
C=π•2r
Now that we have 2r, we can substitute in d:
C=π•d
We know that C=44cm, so we can substitute it in and solve for d:
(44)=π•D
Divide both sides by π:
44/π=D
14.005≈D
Apply the symmetric property
D≈14.005cm
