Question

Find the area of the sector whose radius is 7 cm with the angle 60

Answer 1

Answer:

$Sector \:area (A)=\frac{77}{3}\:cm^{2}$

Step-by-step explanation:

radius of the sector (r) = 7cm

Sector angle (x) = 60°

$Sector \:area (A)\\=\frac{x}{360}\times \pi r^{2}\\=\frac{60}{360}\times \frac{22}{7}\times 7^{2}\\=\frac{1}{6}\times 22\times 7\\=\frac{77}{3}\:cm^{2}$

Therefore,

$Sector \:area (A)=\frac{77}{3}\:cm^{2}$

Answer 2

$\huge\sf{Answer:-}$

Given:-

Find the area of the sector whose radius is 7 cm with the angle 60

Hence,

7 cm is the radius of sector.

60° is the sector angle = (y).

Area = (A)

= y / 360 × πr²

= 60/360 × 22/7 × 7²

= 1/6 × 22 × 7

= 77/3 cm²
