Answer 1

Hey friend.....

Here is your answer....

Circumference of circle =2 pie * r

2*22/7*r=22

r=7/2

Area of quadrant =1/4 pie *r^2

1*4*22/7*7/2*7/2

=8.7cm^2

HOPE that it will help you ✌️

Answer 2

Answer:

77/8 cm²

Step-by-step explanation:

Given, Circumference of circle = 22 cm.

⇒ 2πr = 22

⇒ 2 * (22/7) * r = 22

⇒ 44r = 154

⇒ r = (154/44)

⇒ r = 7/2 cm.

Now,

Area of quadrant = πr²/4

                            = [22 * (7/2)²]/(22 * 4)

                            = 154/16

                            = 77/8 cm²

                            = 9(5/8) cm²

                            = 9.625 cm²

Hope it helps!
