Question

in fig. a circle is inscribed in an equilateral triangle ABC of side 12 cm. Find the radius of inscribed circle and the area of the shaded region.​

Answer 1

Answer:

area of shaded region = (252√3 - 264)/7

EXPLANATION:

HEY MATE YOUR ANSWER IS HERE ^_^

area of the triangle = radius of incircle × semiprimeter = √3/4×(12)^2

r × 18 = √3/4×(12)^2

r × 18 = 36√3

r = 2√3

area of shaded region = area of triangle - area of circle

= √3/4×(12)^2 - 22/7×(2√3)^2

= 36√3 - 264/7

= (252√3 - 264)/7
