The surface area formula for any sphere is 4(pi)(radius)^2

The radius is half of the diameter.

18.6 / 2 = 9.3

So, plug into the formula and solve.

4(3.14)(9.3)^2 = 1086.3 mm^2

$y-36=\frac{18}{5}(x-22)\\\\5y-180=18x-396\\\\y=\frac{18x}{5} -\frac{46}{5}$

$0=\frac{10}{5}x-\frac{46}{5}\\\\x=\frac{216}{18} =12$
