Question

Find the area of a circle with a diameter

Answer 1

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.

Answer 2

64 pi. Half of 16 is 8 and 8 squared is 64.
