Question

the area of quadrant of a circle is 154 cm² find its perimeter step by step​

Answer 1

Answer:

88 cm.

Step-by-step explanation:

=>Area of quadrant of a circle= 154cm

=> 1/4×πr²= 154

=> 1/4 × 22/7 × r²= 154

=> r²= 154× 4× 7/22

=> r²= 7×4×7 (By canceling).

=> r²= 196

=> r= √196

=>r= 14cm

To find the perimeter of the circle:

=>2πr

=> 2×22/7×14

=> 88 cm.
