The equation for surface area for a cylinder is A=2*PI*r*h+2*PI*r^2

A = 2 * 3.14 * 3 * 7 + 2 * 3.14 * 3^2

A = 131.88 + 56.52

A = 188.4 square cm.

The directions are with the pic below. I have to send a 2nd pic. Couldn’t fit everything on the page
Nonamiya [84]

If the pentagon is rotated 360° about the origin, that means the new figure will be exactly in the same position as the original image, because a rotation of 360° about the origin doesn't change the figure position or orientation.

So, if the vertex was located at (10, -8), the new figure will also have a vertex located at (10, -8).

Therefore the correct option is the fourth one.

Find the common ratio of the geometric sequence 6, 48, 384, ...​
gregori [183]

Answer:

r = 8

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{a_{3} }{a_{2} } = ..... = \frac{a_{n} }{a_{n-1} }

Then

r = \frac{48}{6} = \frac{384}{48} = 8
