There is a quarter circle with radius 8cm, what is the area of the quarter circle. The answer should be given in terms of pi, units are cm^2.
The area of a circle is given by the equation: A = pir2 where r is the radiusThis means the area of the quarter circle is just 1/4th the area of the total circle.Therefore the area of the quarter circle is: 0.25 * pi * (8)2 = 16pi cm2
