Hey mate!!!
Here is the answer to your question
Radius of first sphere, r1= 7 cm
Radius of second sphere, r2= 14 cm
Now,
Surface area of sphere = 4¶r^2
Surface area of first sphere =4×22/7×7
=88 cm^2
Surface area of second sphere =4×22/7×14
=176 cm^2
Hope it is correct...
If so, please mark it as brainliest
