Answer:
187.44cm2
Step-by-step explanation:
Given,
Radius = 7cm
Side of equilateral triangle = 14cm
Area of circle =
Area of circle =
Area of equilateral triangle =
Area of equilateral triangle =
=
We know that an equilateral triangle always subtend an angle of 60 at centre area of sector =
=
= = 25.666cm2
This area is common in both the figure so,
Area of shaded region = (area of circle + area of equilateral triangle - 2×area of sector)
= (154+84.77-2×25.67)
= (238.77-51.33) = 187.44cm2
