Question

if a sector of area 462cm2 is cut off from a circle of radius 21cm then the angle of the sector is​

Answer 1

Answer:

Given,

sector area =462 cm

radius =21cm

formulae=?/360×πr^2= area of sector

?/360×πr^2=462

?=90°

Answer 2

Answer:120 degree

Step-by-step explanation:

Area of sector=?/360*22/7*21*21=462

                        =?/60*231=462

                        =?*231=27720

                        =?=27720/231

                        =?=120 degree
