Question

the area of a circle is equal to the sum of the area of two circle whose radius are 5 cm and 12 cm respectively find the radius of the circle​

Answer 1

Step-by-step explanation:

let the radius of the resultant circle be 'R'

using area of circle formula

πr^2 + πr^2 = πR^2

π × 5×5 + π × 12× 12 = πR^2

169π = πR^2

π is cancelled by π

R = ✓169

R = 13

radius of resultant circle = 13 cm
