Question

In a circular garden of 50m radius , a pond is constructed in the form of a circle with radius 20m find the area of the land left out ​

Answer 1

Answer:

Given radius of a circular garden = 50m

Given radius  of the pond that is constructed within the garden = 20m

Area of the land left out = ?

To find the area of the land left out, we need to subtract the area of the circular pond form the area of the circular garden.

Area of the circular garden = πr²    (r = radius)

⇒ 3.14 x 50²

⇒ 3.14 x 2500

⇒ 7850m²

Area of the circular pond = πr²

⇒ 3.14 x 20²

⇒ 3.14 x 400

⇒ 1256m²

Now, the area of the land left out = area of the circular garden - area of the circular pond

⇒ 7850m² - 1256m²

⇒ 6594m²

∴ The area of the land left out = 6594m²

Thnx and have a nice day!
