36 Construct a triangle POR with PO = 7cm
P = hom ind in​

Answer 1

Answer:

96 - 16π cm^2

Step-by-step explanation:

AB=16cm and BC=12cm

AC^2 = AB^2 + BC^2

AC^2 = 16^2 + 12^2

AC^2 = 400

AC = 20 cm

area of triangle

= (1/2)*16*12= 96 cm^2

area of triangle=

(1/2)*16*r +(1/2)*12*r + (1/2)*20*r

= 24r

24r = 96

r = 4

area of circle =πr^2 = 16π

area of shaded region= 96 - 16π cm^2
