Question

length of minor arc in a cirde with R = 28 cm
is 22 cm . Find the measure of the angle
subtended at the centre by this are Also find!
the area of the sectas formed by this are​

Answer 1

Answer:

I =`,x/360. 2πr

22 = x/360x2x22x28/7

central angle

x = 22x360x7/22x28=90 degree

Area of sector = x/360xπr 2

= 90/36ox 22/7x28^2 = 616cm2
