The volume of a cylinder, V, in terms of radius, r,
Igoryamba

Answer:

See explanation

Step-by-step explanation:

Volume of a cylinder = πr²h

Solve for r

V = π * r² * h

r² = V/πh

Find the square root of both sides

r = √V/πh

If height = 6 meters and volume = 300 cubic meters. Find r

r = √V/πh

= √(300/3.14*6)

= √(300/18.84)

= √15.923566878980

r = 3.9904344223381

Approximately,

r = 4 meters

I need help to grab a line this is a stadi G checkpoint it gives you the answer if you do not know it but I don’t want just the
olga55 [171]

The most direct form to graph a line, is to find two points of it and connect them with a line.

Here we have:

y=2x-6

Let's find the point where x = 0. To do this, we replace the x in the equation by 0:

\begin{gathered} y=2\cdot0-6 \\ y=-6 \end{gathered}

We have our first point: (0, -6)

Next let's find the point where y = 0. Again, we replace y in by 0 in the equation:

\begin{gathered} 0=2x-6 \\ 6=2x \\ x=\frac{6}{2}=3 \end{gathered}

We have our second point, (3, 0)

Now all we have to do is plot the points (0, -6) and (3, 0) in the plane, and connect them with a line, and then the line is graphed

The line should look like this:

I need help to find the surface area
Diano4ka-milaya [45]

Answer:

125.6 sq ft.

Step-by-step explanation:

To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:

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

Area of bases: (A=\pi r^{2})

A= \pi 2^{2}

A= 4\pi \\A= 12.56

Since we have two bases, we can simply multiply by 2, giving us:

12.56×2= 25.12

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

Area of the rectangle: (C=d\pi)

C=4\pi\\C= 12.56\\

12.56×8= 100.48

Add these two together, giving us:

100.48+25.12= 125.6 sq ft.
