Ek admi 1 kadam me 77 mitar chalta hai use 1 golakar park ka 1 chakar 400 kadam me pura karta hai to park ka chatrafal kya hoga

Answer 1

Answer:

1kadam =77m

area of circle =π r²

paremeter of circle=2πr

77×400= 2×22÷7 ×r

30800=44÷7×r

r=30800×7÷44

r=700×7

r= 4900 meter

area =π r²

area=22÷7 ×700×700

area=22×100×700

area=1540000meter²
