A trapezium of parellel sides 10cm and 21cm and height 8cm is inscribed in a circle of radius 7cm. calculate the area of the region not covered by the trapezium.
π =227
84cm2
80cm2
30cm2
94cm2
Correct answer is B
Area of circle = πr2 = 227 * 72 = 154cm2
Area o Trapezium = (a+b)h2 = (10+21)82 = 124cm2
Area of the region not covered = Area of (Circle - Trapezium)
= 154 - 124
= 30cm2
