Question

...Q2 please answer.........​

Answer 1

Step-by-step explanation:

Quadrant of a circle means sector is making angle 90.

circumference of the circle=

$2\pi r = 22cm$

Radius of the circle=

$22 \div 2 \pi \:cm = 7 \div 2cm$

Area of the sector making angle 90 =

$(90 \div 360) \times \pi {r}^{2} {cm}^{2}$

$(1 \div 4) \times {(7 \div 2)}^{2} \pi$

$(49 \div 16)\pi \: {cm}^{2}$

$(49 \div 6) \times (22 \div 7) \: {cm}^{2}$

$77 \div 8 {cm}^{2}$
