The diameter of a cylinder is 4 centimeters. The height is 12 centimeters. Using 3.14 for pi, what is the volume of the cylinder
Dovator [93]

Answer:

The volume of the cylinder with given height and radius is 150.72 centimeters³ .

Step-by-step explanation:

Given as :

the height of cylinder = H = 12 centimeters

The diameter of cylinder = D = 4 centimeters

So The radius of cylinder = R = \dfrac{\textrm Diameter}{2}

Or, R = \frac{4}{2}

I.e R = 2 cm

The volume of cylinder is given as V = \pi×R²×H

where R is the radius and H is the height

So, V = 3.14×(2)²×12

Or, V = 3.14×48

∴ V = 150.72 centimeters³

So, The volume is 150.72 centimeters³

Hence The volume of the cylinder with given height and radius is 150.72 centimeters³ . Answer

Write the general equation for the circle that passes through the points (-1,2)(4,2)(-3,4)
Fed [463]

Answer:

x² + y² - 3x - 13y + 18 = 0

Step-by-step explanation:

Recall that the general equation of a circle looks something like this:

x² + y² + Ax + By + C = 0

substituting each of the points into the equation we get:

for (-1,2)

(-1)² + (2)² + A(-1) + B(2) + C = 0

1 + 4 -A+2B + C = 0

-A + 2B + C + 5 = 0 ------------ eq 1

for (4,2)

(4)² + (2)² + A(4) + B(2) + C = 0

16 + 4 + 4A + 2B + C = 0

4A + 2B + C + 20 = 0 ------------- eq 2

for (-3,4)

(-3)² + (4)² + A(-3) + B(4) + C = 0

9 + 16 -3A + 4B + C = 0

-3A + 4B + C + 25= 0 ----- eq 3

Now we have a system of equations with 3 equations and 3 unknowns.

Solving for A, B and C, we eventually get:

A = -3, B = -13, C = 18

Substituting these into the general equation:

x² + y² + Ax + By + C = 0

x² + y² - 3x - 13y + 18 = 0
