The area of the circle is 616 cm2. What is the area of the rectangle?
-
- 784 cm2
- 196 cm2
- 392 cm2
- Cannot be determined
- None of these
Correct Option: C
given :- Area of the circle = 616
⇒ πr2 = 616
Put the value of π = 22/7 in above equation.
we will get,
⇒ r2 = 196
⇒ r = 14 cm
Length of the rectangle = Diameter of the circle = 2r
Breadth of the rectangle = Radius of the circle = r
∴ Area of the rectangle = Length x Breadth
∴ Area of the rectangle = 28 × 14 = 392 cm2
