Question

find the quadrant of a circle whose circumfrenceis22cm​

Answer 1

Step-by-step explanation:

Circumference=22cm

2πr=22

2(22/7)r²=22

2r=7

r=7/2cm

r=3.5cm

As quadrant of a circle is one-fourth of the area of the circle.

Therefore area of quadrant=πr²/4

=(22/7)3.5*3.5*1/4

=11*3.5*1/4

=9.625 cm²

Answer 2

Answer:

Circumference= 2πr

22= 2×22/7× r

22×7/22×2= r

7/2= r

Area of quadrant= πr^2/4

= 154/4

= 77/2 sq cm.
