Area of circular garden with diameter 8 m is
(a) 12.56 m²
(b) 25.12 m²
(c) 50.24 m²
(d) 200.96 m²

Solution:

Given, diameter of circular garden is 8 m

We have to find the area of circular garden

Area of circle = πr²

Where, r is the radius of circle

Radius of circular garden = 8/2 = 4 m

Area of circular garden = 22/7 × (4)²

= 22/7 × 16

= 22(16)/7

= 352/7

= 50.24 m²

Therefore, area of circular garden is 50.24 m²

✦ Try This: Area of circular garden with diameter 4 m is

Given, diameter of circular garden is 4 m

We have to find the area of circular garden

Area of circle = πr²

Where, r is the radius of circle

Radius of circular garden = 4/2 = 2 m

Area of circular garden = 22/7 × (2)²

= 22/7 × 4

= 22(4)/7

= 88/7

= 12.57 m²

Therefore, area of circular garden is 12.57 m²
