BRAINLIST!!!!

The diameter of a circle is 28.26 ft. What is the area?

Answer 1

Answer:

pi(14.13)^2 ft^2

Step-by-step explanation:

Area = pi(r)2

where diameter is 2(r), so r is 1/2 of diameter.

So area is pi(14.13)^2 ft^2

Answer 2

Answer:

A≈627.24ft²

Step-by-step explanation:

d Diameter = 28.26

Using the formulas

A=πr2

d=2r

Solving for A

A=1 4πd2=1 4·π·28.262≈627.24065ft²
