Find r if 0=pi/6 rad sector 64m^2

Given:

Area of a sector = 64 m²

The central angle is .

To find:

The radius or the value of r.

Solution:

Area of a sector is:

Where, r is the radius of the circle and is the central angle of the sector in radian.

Putting , we get

Taking square root on both sides, we get

Therefore, the value of r is m.
