A triangle of height 8cm and base 12cm is inscirbed in a circle of dia 14cm. Find the area of the shaded region
A. 108cm2
B. 90cm2
C. 88cm2
D. 98cm2
For the shaded region's area we need to subtract the area of triangle from the area of the circle.
Area of circle =
=
=
Now area of triangle =
=
= 48 cm2
Area of shaded region = area of circle - area of triangle = 154 - 48 = 106 cm2
Area of circle =
=
=
Now area of triangle =
=
= 48 cm2
Area of shaded region = area of circle - area of triangle = 154 - 48 = 106 cm2
