Question

circumference of a cirlce A is 132 cm.it is equal to the sum of circumference of the two cirlces B and C . the radius of the cirlce B is 14 cm. find the radius of the cirlce C​

Answer 1

Step-by-step explanation:

circle B=2πr=2(π)(14)=28π

let R be the radius of circle C

perimetre of circle C=2πR

perimetre of circle C+perimetre of circle B=perimetre of circle A

2π(14+R) =132

(66/π)-14=R

10.0084=R

radius of the cirlce C=10.0084=R
