Question

the radius of a circle is 8cm and the length of an arc is 16cm then find the area of sector ?

Answer 1

hey mate !!

Answer

$64 {cm}^{2}$

in the questions GIVEN ,

radius of circle is equal to 8cm , and the length of an arc is 16cm.

In the questions we find out area of the sector .

now proceed according to the questions,

angle = length of arc / radius

it's ,

16/8 = 2

again we find the area of sector ,=

${r}^{2} \times \frac{angle}{2} \\ \\ 8 \times 8 \times \frac{2}{2} \\ \\ = 64 {cm}^{2}$
therefore the area's of the sector equal to 64cm^2.

be brainly
