Question

find the area of sector of a circle with radius 6 CM if angle of the sector is 45⁰​

Answer 1

Step-by-step explanation:

Radius of a sector of a circle, r = 6 cm.

Angle of a sector of a circle, θ = 60°

Area of a sector of a circle = ?

Area of a sector of a circle =

\(\frac{\theta}{360}\times \pi r ^2\) =

60/360×22/7×(6)²

1/6×22/7×36

22/7×6=

132/7=18.85²cm

Answer 2

R = 6cm

Theta = 45°

Area of sector ⇒  $\pi$$r^{2}$∅/360°

                       ⇒      22/7×6×6×45°/360°

                       ⇒      22/7×9/2

                       ⇒      198/13

                       ⇒      99/7

                       ⇒      19.14cm
