Question

the diameters of two circles are 32cm and 24cm.find the radius of the circle having its area equal to sum of the areas of the two given circle.

Answer 1

I have sent an image of the solution..
Here,
r1=The radius of the first circle
r2=The radius of the second circle
r3=The radius of the required circle

Answer 2

Step-by-step explanation:

let d1=32 r1=16 A1=?

d2=24 r2=12 A2=?

r3=? A3=?

A.T.O.

A3=A1+A2

πr3²=πr1²+πr2²

r3²=r1²+r2²

r3²=16²+12²

r3²=256+144

r3²=400

r3==20
