Hint: \(\sf\Large Area= 2 \times\pi \times r^2\)

OpenStudy (anonymous):

wait, is it A=πr2

OpenStudy (anonymous):

Ok so what next?

TheSmartOne (thesmartone):

plug in r=9 and pi = 3.14 and just solve.

OpenStudy (anonymous):

28.26?

2 times 3.14 times 9^2 will never even be close to equalling 28.26
