Answer:
We have the formula for area of circle,
Area=π r
2
, where r is the radius of the circle
Let, the circle whose area is equal to the sum of the areas of the two circles of radii 24 cm and 7 cm be A
3
and its radius be r

Step-by-step explanation:
we have ,
dimensions of one radio is 24m and 7m
area 24×7=168
area of two radio=168×2=336
diameter=336×7/22 107.909090.......
