Question

What is the area of the shaded region in the given circle in terms of pi and in simplest form?

Answer 1

can someone help

Answer 2

Area of full circle C = Pi*R^2 = 18^2*Pi = 324 Pi = 1017.36
Area of (shaded area - triangle) : 270*Pi*(300/360) = 270*Pi = 847.8 (1)
Triangle: The height of an equilateral triangle is equal to a*V3/2
Area of triangle: (18)*9V3/2 = 81*V3 = 140.30
Shaded area [( 1) + triangle] = 847.8 + 140.30 = 988.10
Your area is 5/6 of a circle plus the area of the triangle, which is 18^2/4 √3 = 81√3.
