Question

the radius of a circle is 6cm and the area of a sector of this circle is 18 6/7cm² what is the angle of the sector.​

Answer 1

Step-by-step explanation:

angle of the sector=60°

Answer 2

Answer:

Angle of the sector = 60 degree

Step-by-step explanation:

Area of Sector =

$\frac{angle}{360} \times (\pi \times {r}^{2} )$

$\frac{132}{7 } = \frac{angle}{360} \times \pi \times {r}^{2}$

$angle \: = \frac{132 \times 360}{7 \times \pi \times {r}^{2} }$

$angle \: = \frac{132 \times 360 \times 7}{ 7\times 22 \times 36}$

$angle \: = \: {60}^{0}$
