Question

(d) None of these 47. Find the area of the shaded region in figure, if AC = 20 cm, AB = 15 cm and O is the centre of the circle. 22 take it = 7 뤼 A B O (a)95.54 cm? (b)95.45 cm? (c)59.54 cm (d) None of the above ​

Answer 1

Step-by-step explanation:

semi circle area -triangle area

bc^2= 20^2+15^2 = 400+225=625

bc= 25

so radius =25/2

area of semi circle =(1/2)* (22/7)*(25/2)*(25/2)

= 245.5

area of the triangle = 1/2 *20*15= 150

so shaded area= 245.5-150= 95.5
