Area of circular garden with diameter 8 m is ______.
पर्याय
12.56 m2
25.12 m2
50.24 m2
200.96 m2
उत्तर
Area of circular garden with diameter 8 m is `bb(underline(50.24 cm^2))`.
Explanation:
Given, diameter = 8 m
So, radius = `8/2` m = 4 m ......`[∵ "Radius" = "Diameter"/2]`
∴ Area of circular garden = πr2 = `22/7 xx 4 xx 4` = 50.24 m2.
