Find the area of shaded region where diameters are given in the figure.
Answers
Answer:
The area of shaded region = 57.75 cm²
Step-by-step explanation:
Given : Diameter D of big semi circle = 14 cm
Dimeter d of smaller circle = 7 cm
Solution : Area of shaded region = Area of big semi circle - area of small
semi circle
= (π x D²/8) - (π x d²/8)
= 22/( 7 x 8) x ( 14² - 7² ) ∵ π = 22/7
= 22/56 x (196-49)
= 22 x 147/56
= 57.75 cm²
