Question

16) The area of the minor sector of the circle is equal to 5/18 the area of the 1 point
circle. Find the corresponding central angle.
100°
120
60°
80°​

Answer 1

let r be the radius of circle and A be the minor angle in degree

given

πr^2(A/360°) = 5/18 * πr^2

A/360 = 5/18

A = 5/18 * 360

A = 100°
