This exercise involves the formula for the area of a circular sector Find the radius r of each circle the area of the sector is 12. (a) 5 rad. (b)

Solution

Solution:
Degrees = (radians × 180° / )
Given Central angle(in radian )= 0.5
We have to convert radian into degree.
A = 0.5 ×180 / )

=> Area of sector = r²A/360, A = central angle

=> (r²0.5×180)/(360 × )

= (r²× 5)/20 =12(Given)

=> r² = 240/5

=> r²= 48

=> r = 43.
