How do you find the diameter

Answers

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.

find the equation of the line passing through points (-4,2) and (1,-6)

Answers

Answer:

y + 6 = (-8/5)(x - 1) in point-slope form

Step-by-step explanation:

Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8.  Thus, the slope of the line through these two points is m = rise / run = -8/5

Now we have two points on the line, plus the slope.  Let's write out the point-slope formula for the equation of a straight line:

y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

Here, using the point (1, -6), we obtain:

y + 6 = (-8/5)(x - 1) in point-slope form

Find the volume of the cylinder.
Either enter an exact answer in terms of
π
πpi or use
3.14
3.143, point, 14 for
π
πpi.

Answers

Answer:

Solution :-

Radius is 3

Height is 2

So,

Volume = πr²h

Volume = 3.14 × (3)² × 2

Volume = 3.14 × 9 × 2

Volume = 3.14 × 18

Volume = 56.5 units²

Answer: 56.52

Step-by-step explanation:

You can get a volume of a cylinder by multiplying pie which is 3.14 by radius squared multiplied the height...

The equation is Volume = πr²h

Or in simpler terms:

3.14 × radius ×radius × height

So the final equation is:

3.14 × 3² × 2

=56.52
