Question

If the area of quadrant of a circle is 22cm2

, find its perimeter.​

Answer 1

Answer:

P. = 33.3 cm ( approximately )

Step-by-step explanation:

Area of circle = 4 × Area of quadrant

22/7 × r2 = 4 × 22

{ Here, 22 will get cancelled from both sides. The 7 in the left shifts to right and gets multiplied by 4 and gives 28. }

r2 = 28

r = root 28.

r = 5.3 cm ( approximately )

Perimeter (P.) = 2 × 3.14 × 5.3

P. = 2 × 16.642 = 33.284

P. = 33.3 cm ( approximately )
