Question

find the area of minor segment of a circle of radius 28cm when angle of the corresponding sector is 45 degree

Answer 1

area of minor segment = πr² x angle /360
3.14 x 28 x 28 x 45/360
2461.76 x 1/8
= 307.72 cm²

Answer 2

Answer:

308 cm².

Step-by-step explanation:

A circle consists 360° angle as a whole,

A minor segment which has an angle of 45° will be (45°/360°) = 1/8th part of the whole circular area.

Area of the circle = πr² = π(28)² = (22/7)(28)² = 2464 cm²

Thus the area of the segment = (2464/8) = 308 cm².
