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!

Rate of change on a graph.- I'll give brainly for the answer, thank you

Answer:

The slope of graph is $\mathbf{\frac{3}{2}}$

Option C is correct option.

Step-by-step explanation:

We need to find the slope (rate of change) of the graph

The formula to calculate slope is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Taking two points from the graph: (You can take any two points from the graph)

Point 1 (-4,-3)

Point 2 (-2,0)

We have: $x_1=-4, y_1=-3, x_2=-2, y_2=0$

Putting values in the formula and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-3)}{-2-(-4)} \\Slope=\frac{0+3}{-2+4} \\Slope=\frac{3}{2}$

So, the slope of graph is $\mathbf{\frac{3}{2}}$

Option C is correct option.

Volume of a sphere r=5

Reptile [31]

V = 4/3 (3.14) (5) to the third power 3
(5)3rd = 125
4/3 x (3.14 x 125)
3.14 x 125 = 392.5
4/3 x 392.5 = 1570 / 3
Volume = 523.33
