What number must be added to 15,-6, and 12 to have a mean of 5? Explain.

Genrish500 [490]

You need to add a -1

We can find this by setting up the equation like so

x + (-6) + 12 + 15 / 4 = 5

x + 21 = 20

x = 20 -21

x = -1

Now if we insert -1 where x is located in the equation, you will get a means of 5

What is the surface area of the cylinder with height 4 mi and radius 3 mi? Round your answer to the nearest thousandth.

Norma-Jean [14]

Answer:

The surface area of the cylinder will be "131.88".

Step-by-step explanation:

The given values are:

Height of cylinder,

h = 4 m

Radius of cylinder,

r = 3 m

As we know,

The surface are of cylinder is:

⇒ $A_s=2 \pi r(h+r)$

On substituting the values, we get

⇒ $=2\times 3.14\times 3(4+3)$

⇒ $=18.84\times 7$

⇒ $=131.88$
