Question

Find the area inside the semicircle and out side the triangle in terms of ń

Answer 1

π 169 / 2 - 120

Explanation:

I'm assuming you are asking question about 24.

So first find radius of semicircle:

a^2+b^2=c^2

10^2+24^2=c^2

c=26

radius 26/2 = 13

Then let's calculate area of semicircle

area of circle = π*r^2

area of semicircle = π*r^2 / 2

area of given semi circle = π 169 / 2

Then let's calculate area of triangle

area of triangle = 10 * 24 / 2 = 120

Area of the shaded region = π 169 / 2 - 120
