1. Your answer is correct. The 136 feet will make the circumference of a circle which is 2*pi*R where R is the radius, so you can calculate the radius of the circle by dividing 136 by 2*pi. Next, you can obtain the area of this circle, which will be the same as the area of the pond, by using the formula Area = pi*R^2. Try it out!

4. no, your choice is not correct

circumference = 136
2πr = 136
r = 68/π

area = π r^2
= π(68/π)^2 = 1471.86
