Answer:

Explanation:

The circumference of a circle in terms of the diameter is

$C=\pi d$

If our diameter is 29 feet, then the circumference, in terms of pi is

$C=29\pi ft$ .

If we are multiplying in pi as 3.14, then it is

C = 91.06 ft

The area formula for a circle is

$A=\pi r^2$

If the diameter is 29, then the radius is half of that at 14.5 feet. Filling in:

$A=\pi(14.5)^2$

so, in terms of pi, the area is

$A=210.25\pi ft^2$ or if you multiply pi in as 3.14, then you get:

A=660.185 ft^2
