Question

The following is a compound plane figure consisting of a parallelogram and a sector of a circle

• A. undefined
• B. undefined
• C. undefined
• D. undefined

Answer 1

i) Area of the parallelogram
$=base\times height=30\times 7=210c{m}^2$

ii) Area of a sector =$\frac{\pi r^2\theta }{360}=\frac{22}{7}\times \frac{{14}^2\times 150}{360}22\times 2\times 14\times \frac{5}{12}=\frac{770}{3}c{m}^2$

iii) sum of both the radius of the sector
