The circumference of a circular park is 352 m. Find the area of the park
उत्तर
Circumference of a Circle = 2πr units
Given circumference of a circular park = 352 m
2πr = 352
`2 xx 22/7 xx "r"` = 352
r = `352 xx 7/22 xx 1/2` = 56 m
Area of the park = πr2
= `22/7 xx 56 xx 56 "sq.units"`
= 22 × 8 × 56
= 9856 m2
∴ Area of the Circular park = 9856 m2
