Leave a message at the tone

To see if both our schedules are free

Angel numbers, yeah I know

Only numbers on my phone

And if I like it, I'll take two

That same cover since day one

And if she ask me, yes I jump

We're cancer, gemini, what's up?

Never ever switching up

A cylinder has a height that is twice the length of the diameter. The diameter of the cylinder is 10 centimeters. What is the su

siniylev [52]

Answer:

Step-by-step explanation:

Givens

pi = 3.14

d = 10 cm

h = 2*d

Formula

The top of the cylinder is a solid circle. So the area of the circle is pi r^2
There is both a top and bottom to the circle so the fomula is 2*pi*r^2

The surrounding area of the cylinder is the circumference of the circle times the height. The circumference of the circle is 2*pi*r.
Then you just multiply by the height.
formula = 2*pi * r * h

The combined formula is given below.

SA = 2*pi*r^2 + 2*pi*r * h

Conversions

d = 10 cm

h = 2*10

h = 20 cm

r = d/2

r = 10 / 2

r = 5cm

Solution

SA = 2*pi*r^2 + 2*pi*r * h

SA = 2*3.14*5^2 + 2*3.14*5*20

SA = 157 + 628

SA = 785 cm^2

Answer: The surface area is 785 cm^2

What is the product of 3x-4+x^2-1+2x^2-15

spayn [35]

3x - 4 + x^2 - 1 + 2x^2 - 15
3x^2 + 3x - 20
I wasn't sure if you wanted me to solve for x, but I did anyways.
x ≈ 1.86, or -2.86
