The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 5 mm. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth. A cylinder and 2 half spheres. All have a radius of 5 millimeters. The cylinder has a height of 10 millimeters. Recall the formulas V = B h and V = four-thirds pi r cubed 376.80 cubic millimeters 847.80 cubic millimeters 1,177.50 cubic millimeters 1,308.33 cubic millimeters

Answer:

$1308.33 {mm}^(3)$

Step-by-step explanation:

The volume of the composite shape is given by:

Volume of cylinder +volume of two spheres.

The volume of cylinder

$= \pi \: {r}^(2) h$

We substitute r=5mm and h=10mm

The volume cylinder becomes

$= \pi \: * {5}^(2) * 10 \n = 250\pi$

$= 250 * 3.14 \n = 785 {mm}^(3)$

The volume of the two hemispheres

$= (4)/(3) \pi {r}^(3)$

We substitute the radius to get:

$= (4)/(3) * \pi * {5}^(3) \n = 523.33 {mm}^(3)$

We add the two volumes to get:

$= 785 + 523.33 = 1308.33 {mm}^(3)$

Is y = 0.5x - 1 a liner function

Answers

Yes equation is a linear function.

What is linear function?

A linear function is one that has either one or two variables and no exponents. It is a function with a straight line as its graph. Any equation follows the y = ax +b is linear.

given an equation y = 0.5x -1

so Any equation follows the y = ax +b is linear.

and graph has straight line for linear equation

here a = 0.5; b = -1

Slope intercept form is y=mx+b. Any equation in this form is linear.

Step-by-step explanation:

if it was x squared it is not linear, its quadratic, so if there is ever an equation with just an x its linear. any x that has an exponent that's is not 1 is not linear. Hope this makes sense.

5/6 - 1/6 =
in simplest form

Answers

5/6 - 1/6 forget about the denominator since it's the same denominator
5 - 1 = 4
4/6 is the answer and 2/3 simplified :)

5/6 - 1/6 = 2/3
5-1=4 keep the dinominator. so u have 4/6. simplify by 2 , 4/6÷2=2/3

You increase the size of a page by 50%. Then you decrease it by 50%. What is the size of the page now?

Answers

We can't tell what size the page is now, because you never told us
what size it was before all the shenanigans started. All you gave us
was a couple of ratios.

And you didn't even tell us WHAT was increased and decreased ...
was it the length of the sides, or was it the area of the page ?
__________________________________________

If it was the length of the sides ...

Let's say the page was 8" high and 4" wide.

Increase lengths by 50% :   Now it's 12" high and 6" wide.

Decrease lengths by 50% :   Now it's 6" high and 3" wide.

   The sides are now 3/4 as long as they started out,
   and the area is 9/16 of what it started out.
