Answer:

Second option: Surface area = 176*pi cm2

Step-by-step explanation:

The surface area of a cylinder is given by:

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

Where r is the base radius and h is the height.

If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:

S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2

So the answer is the second option.

The sum of 5 consecutive numbers is 200. What is the smallest number?

Vikentia [17]

Answer:

Hey!

Your answer is 44!

Step-by-step explanation:

Here's how...

x+(x+2)+(x+4)+(x+6)+(x+8)=200

5x+20=200 (minus 20 on both sides to get 5x by itself)

5x=180 (divide both sides by 5 to get just x)

x=36

5th number - x+8=36+8=44 (simple substitution and addition)
