Question

If the radius of the circle is 6 cm and the length of an arc is 12 cm find the area of sector

Answer 1

Given radius = 6cm and the length of the arc = 12cm.

We know that Area of sector = LR/2

                                                 = 12 * 6/2

                                                 = 72/2

                                                 = 36cm.


Therefore the area of sector = 36cm.


Hope this helps!

Answer 2

Hey there!!

We have ,

Radius , r = 6cm

length. of the arc , l = 12

Area of sector , =
$\frac{l \: r}{2}$
putting = 12 and r = 6 cm

so
$\frac{12 \times 6}{2} \\ \\ = \frac{72}{2} \\ \\ = 36 \: {cm}^{2}$
Hope this helps you !
