ans this question​

Answer 1

Answer:

according to the question,

first and second cirlce = new circle

or, 2πr + 2πr = new circle

or, 2* 227 * 28 + 2 * 22/7 * 18 = new circle

or, 176 + 113.14 = new circle

or, 289.14 = new circle

again, new circle = 2πr

or, 289.14 = 2* 22/7 * r

or, r =46

hence, radius of new circle is 46cm
