Find the area of a circle with a diameter
of 16.
Either enter an exact answer in terms of a
or use 3.14 for a and enter your answer as
a decimal.

To get the answer divide the diameter by two, so you can get the radius. So plug it into the formula A=π 8²=π (8²)=64π =200.96 and for multiplying pie I just used 3.14 instead the entire number so I could get it  by having the decimal in the hundredths place.
