Find the surface area of the cylinder to the nearest tenth. Use 3.14 for n
zaharov [31]
Remember: The formula for surface area for cylinders are S= 2πrh + 2πr²
 The 2πr² represents the circular parts of the cylinder. 

First, let's find the lateral side of the cylinder. 
→ 2 (3.14)(6)(15) = 565.2
Next, find the circular parts.
→ 2 (3.14)(6²)
→ 2 (3.14)(36) = 226.08
Add the two answers together.
→565.2 + 226.08 = 791.28
Round.
Your final answer is 791.3 in²
I hope this helps!

Where would (0.5,2) be potted ? Please answer this !!
NISA [10]

 (0.5,2)

0.5 is x value

2 is y value

         l

         l

---------------

        l

        l

x value is on dashed line (0.5)

y value is on more separated line going up and down. (2)

To plot 0.5, you can put it as an equation. 0.5= 1/2. So to plot it, 0.5 is half of 1. So plot it as in between the 1 and 0.

To plot 2 go up to the two on the y axis and then go over 0.5 and plot a point.

That is you're plotted point for (0.5,2)


Hope it helps!
