Question

The area of circle of radius 3 cm is
31
Ou​

Answer 1

Answer:

28.285 sq.cm

Step-by-step explanation:

Area Of Circle =

$\pi \: r ^{2}$

$\frac{22}{7} \times {3}^{2}$

$\frac{22}{7} \times 3 \times 3$

$\frac{198}{7}$

$28.285$

Answer 2

Perimeter of a sector of circle =31cm

Radius=6.5cm

Arc Lenght=31-(6.5+6.5)=18cm

Now, area pf sector =1/2×arc lenght=1/2×2

18×6.5=58.5cm
