201.06m sound better?

OpenStudy (anonymous):

The area of a circle is:\[A = \pi \times r ^{2}\] r, the radius is half of the diameter.

OpenStudy (anonymous):

To do this problem, first identify your diameter. That is the span of the circle, from side to side, and that is 16.

OpenStudy (anonymous):

i got 113.04???

OpenStudy (anonymous):

Take half of that diameter, then square it. Take that resulting number and multiply it by pi, which is:\[\pi \]and you can use 3.14 for the value of pi.

OpenStudy (anonymous):

\[3.14\times 8^2=201?\] i rounded

OpenStudy (anonymous):

Very good!
