-6.

Step-by-step explanation:

Please help!!! I really don’t get this only I get where the 3 are but please help me for the 4/5 and -0.4!

Naily [24]

Answer:

-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.

3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.

Step-by-step explanation:

I hope you understand what I mean.

HELP ASAP THIS IS STRESSING ME OUT!

The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.

If the radius of the base is $r$ and the height is $h$ , then the surface area of the cylinder is

$A=2\pi r^2+2\pi rh$

You're given that the area is $96\pi$ and the radius is $4$ , so you have

$96\pi=2\pi\times4^2+2\pi\times4h\implies 12=4+h\implies h=8$
