Answer:
80km
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (1.2, 1.0, 96) as shown below:
Next we cross multiply. We multiply 1.2 and x, and we multiply 96 and 1.0.
1.2(x) = 1.2x
96 x 1.0 = 96
Now, lets put the values above back into the equation:
1.2x = 96
Lets solve this equation. First we divide 96 by 1.2.
1.
2.
This means that our answer is 80km.
The surface area of a sphere is 
and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.
For example, let us assign values.
Let A=90
A= 90*9 = 810
and 
the first r is 2.68 and the second r is 8.03
then,
or rounded off to 3.
For example, let us assign values.
Let A=90
A= 90*9 = 810
the first r is 2.68 and the second r is 8.03
