Question

the area of quadrant of a circle whose circumference is 22m is​

Answer 1

Answer:

9.625{cm}^{2}

Step-by-step explanation:

Given:

Circumference of cicrle = 22 cm

We know that

Circumference of circle = 2\pi r

22 cm = (2 × 22 × r)/7

7 cm = 2r

r = 3.5 cm

Area of quadrant = (\pi {r}^{2})/4

= ((22 × 3.5 × 3.5)/7)/4

= (11×3.5)/4

= 38.5/4

= 9.625 {cm}^{2}
