How to solve this problem in the picture above

g=4

Step-by-step explanation:

If you're solving for g, you need to get it alone on one side. The way I did so was to subtract 7 from each side.

15 = 2g + 7

-7            -7

If you do that, the 7 on the right cancels out and you're left with 8 = 2g. To get the g alone, you divide it by it's base on both sides which in this case is 2.

8/2 = 2g/2

That will cancel the 2 out and will leave you with g on the right side and on the left side would be 4 because simple division (8/2=4)

Your final answer should be g = 4

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
