Question

find the radius of a circular field
whose cricumference is 2.2 km​

Answer 1

Answer:

Step-by-step explanation:

Answer:Circumference of a circle is 2πr

Therefore : 2.2=2×π×r

1.1=π×r

1.1×7/22=r

7.7/22=r

0.7/2=r

0.35Km=r

Answer 2

Step-by-step explanation:

Circumference of the circle = 2.2 km

=> 2πr = 2.2 km

=> πr = 2.2/2

=> πr = 1.1

=> 22/7 × r = 1.1

Therefore, r = 1.1 ÷ 22/7

= 1.1 × 7/22

= 7.7/22

= 77/220

= 0.35 km

= (0.35 × 1000) m

= 350 m

Hope it helps :)
