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

alexgriva [62]

<h2>Answer:</h2>

<em>Rounded to the nearest hundredth the volume of the composite figure is:</em>

<em>1308 33 cubic millimeters</em>

<h2>Explanation:</h2>

Hello! I wrote the complete question in a comment above. The volume of a cylinder is defined as:

$V_{c}=\pi r^2 h \\ \\ r:radius \\ \\ h:height$

While the volume of half a sphere is:

$V_{hs}=\frac{2}{3}\pi r^3$

Since we have 2 half spheres, then the volume of these is the same as the volume of a sphere:

$V_{s}=\frac{4}{3}\pi r^3$

Then, the composite figure is:

$V=\pi r^2 h +\frac{4}{3}\pi r^3 \\ \\ V=\pi r^2(h+\frac{4}{3}r)$

The radius of the cylinder is the same of the radius of each half sphere. So:

$r=5mm \\ \\ h=10mm \\ \\ \\ V=(3.14) (5)^2((10)+\frac{4}{3}(5)) \\ \\ V=25(3.14)(10+\frac{20}{3}) \\ \\ \boxed{V\approx 1308.33mm^3}$

Sarita used 54 ounces of apples to make an apple pie.How many pounds and ounces of apple did sarita use?

Inga [223]

Answer:

Step-by-step explanation:

16 ounces is equal to 1 pound

Divide 54 by 16 and you get 3.375

You know that there are 3 pounds now, so subtract 3 from what you got to get 0.375

Now multiply 0.375 by 16 to turn it back into ounces, which is 6

3 pounds and 6 ounces is answer choice C

If f ( x ) = 3x² - 5x + 7 , Show that f ( -1 ) = 3 f ( 1 ) .<br><br><br><br><br>Tysm :')

Lelechka [254]

Solution :

3x² - 5x + 7

put x = -1

3(-1)² - 5(-1) + 7

3(1) + 5 + 7

3 + 12

Now, put x = 1

3(1)² - 5(1) + 7

3(1) - 5 + 7

3 + 2

here :

f(-1) = 15

f(-1) = 3(5)

f(-1) = 3 f(1)

Question 11 . 2 p Brent is considering buying a new circular track for his model train. He estimates that the model's circumfere

neonofarm [45]

Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.

<h3>What is a circle? </h3>

A circle is the locus of a point, such that the distance from a fixed point (center) is always constant.

The circumference of a circle is given by:

Circumference = π * diameter

Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.
