Question

Find the area of the shaded parts of the figure?

Answer 1

Answer:

First equate the arc length to the formula and get the angle and apply that angle on area formula

Answer 2

Hi friend here is your answer

One side of the triangle = 12cm

Second side = 12cm

Since the second side is a radius from the middle of the circle the same measure goes for the third side also. So therefore this is an equilateral triangle. As it is an equilateral triangle it's angles will be 60° each.

Area = 1/2* (l+b)

= 1/2*(12+12)

= 1/2*24

= 12 sq.cm

This is how I find it if your equations are different just use the sides and be sure that it's an equilateral triangle
