1.	A garden is built in the shape of a circle of 22 meters in diameter. There is a circular section of 4 m radius for the playground in the center of the garden. This circular ring made is said to be covered by grass. Find the area of this circular ring in square meters.A. 1470.8B. 572.6C. 330D. 707.141. A2. B3. C4. D
Answer» Correct Answer - Option 3 : C Given: A garden diameter is 22 m A playground having radius of 4 m Formula used: Area of circle = πr² where, r is Radius of the circle Calculations: The radius of the garden is 22/2 = 11 m According to the question, we have The area of the garden is ⇒ Area = (22/7) × 11 × 11 ⇒ Area = 380.28 m² And, Radius of the playground is 4 m The area of the playground is ⇒ Area = (22/7) × 4 × 4 ⇒ Area = 50.28 m² The remaining area is ⇒ Remaining area = 380.28 - 50.28 ⇒ Remaining area = 330 m² ∴ The remaining area of a circular field is 330m².

Answer» Correct Answer - Option 3 : C

Given:

A garden diameter is 22 m

A playground having radius of 4 m

Formula used:

Area of circle = πr²

where,

r is Radius of the circle

Calculations:

The radius of the garden is 22/2 = 11 m

According to the question, we have

The area of the garden is

⇒ Area = (22/7) × 11 × 11

⇒ Area = 380.28 m²

And, Radius of the playground is 4 m

The area of the playground is

⇒ Area = (22/7) × 4 × 4

⇒ Area = 50.28 m²

The remaining area is

⇒ Remaining area = 380.28 - 50.28

⇒ Remaining area = 330 m²

∴ The remaining area of a circular field is 330m².
