The area of a semicircle is _____(a) \(\frac {2\pi r}{2}\)(b) \(\frac {2\pi r}{2}\)(c) \(\frac {\pi r}{2}\)(d) \(\frac {\pi r^2}{2}\)This question was addressed to me by my school principal while I was bunking the class.This interesting question is from Perimeter and Area of a Circle topic in section Area Related to Circles of Mathematics – Class 10

Answer»

Correct OPTION is (d) \(\FRAC {\pi r^2}{2}\)

Easy explanation: A semicircle is half of a full circle. HENCE, the area of a semicircle is ALSO half of a circle. Half of πr^2 is \(\frac {\pi r^2}{2}\). Therefore, the area of a semicircle is \(\frac {\pi r^2}{2}\).
