Answer:
about 706.5 or 706.86
Step-by-step explanation:
to find this answer we need to use the area formula of a circle which is A = πr ^2
we know the diameter is 30, and the radius is half the of diameter, so we take 30 and divide it by 2, which should give us 15 for the radius. ( 30/2 = 15, so r = 15)
depending on how your teacher wants u to answer this you can use π on a calculator or use 3.14
now just plug in your numbers to formula
A = 3.14 * 15^2 or A = π * 15^2
and should equal about 706.5 or 706.86 (depending on if you use 3.14 or π)
