Question

In a circular park with a radius of 210m there are 7 lamps whose bases are circles with a radius of 1m.
The entire area of the park has grass with the exception of the bases for the lamps. Calculate the area of the
lawn. (π=22/7 )

Answer 1

Answer:

133980

Step-by-step explanation:

Area of the total circular park - 7(area of lamps)

π×210×210 - 7(π×1×1)

22×30×210 - 22

133980 m²
