Detailed Solution

Given, a circular garden with a diameter 8 m.
We know that the area of a circle with ‘r’ radius is given as

π r 2

.
So, as we know that the radius is half the diameter, then we have r =

82 = 4

cm.
So, we have the area of the circular garden as follows,

= π × 42 = 227 × 16 = 50.24 m 2

So, the area of the circular garden is obtained as 50.24

m 2

.
Hence, the correct option is (3).
