Question

Area of right angled triangle with inradius and circumradius

Answer 1

Formula for calculating the inradius of a right angled triangle can be given as r = ( P + B – H ) / 2. And we know that the area of a circle is PI * r2 where PI = 22 / 7 and r is the radius of the circle. Hence the area of the incircle will be PI * ((P + B – H) / 2)2.
