Question

14. Find the area of sector of a circle with
radius 4 cm and angle 60°..​

Answer 1

Answer:

Step-by-step explanation:

Radius of circle (r) = 4 cm

Angle of sector r(θ) = 60

Area of sector=pieR^2/360=8.37 (approx)

Answer 2

$\sf \dfrac{8}{3}\pi \: cm {}^{2}$

Step-by-step explanation:

$\sf \: Area \: of \: Sector = \pi\: ( Radius) {}^{2} \times \dfrac{ angle}{360}$

Now,

Radius = 4 cm

Angle = 60°

$= \pi {(4)}^{2} \dfrac{60}{360} \\ \\ = \frac{16\pi}{6} \\ \\ = \sf \: \frac{8}{3}\pi \: cm {}^{2}$

Answer is 8/3π cm²
