Question

a meteor falls near village creating a circular pit of diameter 200 m find the area of the affected land.

Answer 1

d= 200m
r=100m
Area of circle=πr^2
22/7×100^2
22/7×10000
31428.5714285714m^2 is the area of the affected land.
Hope u got it right.
Plzzz mark as brainliest.

Answer 2

Dear Student,

◆ Answer -

A = 31416 m^2

● Explanation -

Radius of circular pit is given by -

r = d/2

r = 200/2

r = 100 m

Area of the affected land is -

A = πr^2

A = 3.1416 × 100^2

A = 3.1416 × 10000

A = 31416 m^2

Hence, the area of the affected land is 31416 m^2.

Thanks dear. Hope this helps you...
