\sf\small\underline\red{Solution:-}
Solution:−
To calculate the radius of new circle at first we have to assume the radius of 1st circle be r¹ and the radius of 2nd circle be r². The radius of new circle be r. According to given question we have to set up equation. Then applying the formula of area of circle to calculate the radius of new circle. Here the radius of 1st circle be 10cm and the radius of 2nd circle be 6cm.
