Find the degree measure of the angle subtended at the center of a circle of radius 100 cm by an arc of length 22 cm. (Useπ= 22/7 )/ |
|
Answer» We know that in a circle of radius R UNIT, if an arc of length L unitsubtends an angle θ radian at the centre, then θ= rl Therefore, for r=100 cm, l=22 cm, we haveθ= 10022 radian= π180 × 10022 degree= 22×100180×7×22 degree= 10126 degree=12 53 degree=12 ∘ 36 ′ ,[∵1 ∘ =60 ′ ]Step-by-step explanation: |
