Question

e.
5. Find the circumference of a circle whose area is 7546 sq.cm. ​

Answer 1

Answer:

86

Step-by-step explanation:

Make the pair of last 2 digit 46 and rest 2 digits 75

check 46>6×6

75>8×8

Then answer makes 86....

Answer 2

Step-by-step explanation:

let the raidus of the circle be x

Area of circle=pi×R^2 (use pi symbol if you're writing)

But,area of circle=7546 cm^2(given)

A/Q => pi × x^2 = 7546

=> 22/7 × x^2=7546

=> x^2 = 7546 ÷22/7

=>x^2 = 7546 × 7/22

=> x^2 =2401

=> x=√2401

=>x =49

hence,radius=49 cm

circumference=2×pi×R

circumference = 2×22/7 × 49=308cm
