Question

The radii of two circles are 17 cm and 7 cm respectively. Find the radius of the circle which has been

circumference equal to sum of the circumference to the two circles​

Answer 1

Answer:

24

Step-by-step explanation:

given radii of two circles are 17 cm and 7 cm respectively.

circumference of first circle=2π(17)

circumference of second circle= 2π(7)

let the circumference of unknown circle= 2πr

now, 2πr= 2π(17) + 2π(7)

2πr=2π(17+7)

r= 17+7

r= 24 cm
