Question

area of circular field is 13. 86 metre square find the circumference of the field

Answer 1

As we know that ,

Area of circle = ( πR² )

So,

13.86 = ( πR) ²

22/7 × R² = 13.86 cm

R² = 4.41

R = √4.41

R = 2.1 m

Therefore,

Circumference of circular Field = 2πR

=> ( 2 × 22/7 ×2.1 )m

=> 13.2 m

αяєα σf ¢ιя¢υℓαя fιєℓ∂ = 13.86 м²

πя² = 13.86

22/7 × я² = 13.86

я² = 4.41

я = √4.41

я = 2.1 м

яα∂ιυѕ σf ¢ιя¢ℓє = 2.1 м

¢ιя¢υмfєяєи¢є σf ¢ιя¢ℓє = 2πя

=> 2 × 22/7 × 2.1

=> 13.2 м
