For a cylinder there is 2 kinds of formulas the lateral and the total. the lateral surface area is just the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.

The equation for the surface are of a cylinder is 2 pi r h +2 pi r ^2
That’s means the equation is 2 pi 30 + 2 pi 9 which equals 245cm

True [87]

Answer:

<h2>10 units</h2>

Step-by-step explanation:

It's important to know that the centroid is always two-thirds of the median. Which means

$AG=\frac{2}{3}FA\\ x+9=\frac{2}{3}(5x+x+9)\\ x+9=\frac{2}{3}(6x+9) \\x+9=4x+6\\9-6=4x-x\\3x=3\\x=1$

Which means $AG=x+9=1+9=10$ .

But, the centroid has always the same distance from each vertex, which means

$AG=BG=10$

Therefore, BG is 10 units long.
