Question

the cost of leveling of the ground of a circular region at a rate of paisa 25 per square meter is Rs 2500 find the radius of this ground

Answer 1

Answer:

Radius = 8 mtr.

Step-by-step explanation:

Amount Per square metre = 25 paisa = 25÷100= 0.25 Rs

Total money spent = 2500 Rs

Area of the ground= 2500÷0.25

= 10,000 square mtr.

ATQ:-

πr2= 10,000

r2= 10,000÷π

r2 = 10,000÷22/7

r2= 64

r2=(8)2

r= 8
