Question

From the measure given below, find the area of the sector 1) find the area of the arc = 48m, 10m

Answer 1

Answer:

(i) Area of the sector A = lr/2 sq. units l = 48 m r = 10 m = (48 × 10)/2 m2 = 24 × 10 m2 = 240 m2 Area of the sector = 240 m2 (ii) length of the arc l = 12.5 cm Radius r = 6 cm Area of the sector A = lr/2 sq. units = (12.5×6)/2 = 12.5 × 3 cm2  = 37.5 cm2 Area of the sector = 37.5 cm2 (iii) length of the arc l = 50 cm Radius r = 13.5 cm Area of the sector A = lr/2 sq. units = (50×13.5)/2 = 25 × 13.5 cm2 = 337.5 cm2 Area of the sector = 337.5 cm2Read more on Sarthaks.com - https://www.sarthaks.com/977996/from-the-measures-given-below-find-the-area-of-the-sectors?show=978005#a978005
