Question

the area of a circle is 528m sq.find its circumference.π=22/7

Answer 1

Area of circle = 528 m



πR² = 528



22 / 7 × R² = 528


R² = ( 528 × 7 ) / 22

R² = 168


R = √168


R = 12.96 cm.


Therefore,

Circumference of circle = 2πR = 2 × 22/7 × 12.96 = ( 2 × 22 × 12.96 ) / 7 = 570.24/7 = 81.46 cm².

Answer 2

HEY MATE HERE IS YOUR ANSWER

$<b>$Given :-

Area of circle :- 528 m

We know that,

Area = pie r^2 = 528

22/7 × r^2 = 528

R^2 = 528 × 7/ 22

R^2 = 168

R = 12.96 cm

And we also know that,

Perimeter of circle :- 2 pie r

➡️ 2 × 22/7 × 12.96

➡️ 81.46 cm^2.


Hope it will help you
