Acircular rug has an area of 32.15 . what is the diameter of the rug, to the nearest tenth of a foot? plz show work and explain.
a. 8 feet
b. 16.1 feet
c. 3.2 feet
d. 6.4 feet

Diameter is twice the radius.  A=πr^2.

First, solve for r:

32.15=πr^2

*Divide both sides by π*

10.2337=r^2

*Take the square root of both sides*

3.199=r

Multiply the radius by 2:

3.199*2=6.398

D. 6.4 feet

Hope this helps!!
