hartnn (hartnn):
Area of circle is just \(A = \pi r^2\) so, just square the radius and write it besides pi!
OpenStudy (anonymous):
so if the diameter of the circle is 14 the answer would be 196pi?
hartnn (hartnn):
the 'r' there is the radius! and diameter = 2* radius so your radius will be 14/2 = 7 and area will be just 49 pi got this ?
OpenStudy (anonymous):
yes! thank you
hartnn (hartnn):
welcome ^_^
