A right circular cylinder has a diameter of 16 mm and a height of 12 mm. what is the volume of the cylinder in terms of π?

Mathematics

valina [46]3 years ago

Volume of the cylinder = hr²π

diameter = 2 × radius
16 = 2 × r
r = 16/2
r = 8 mm

V = hr²π
V = 12 × 8² × π
V = 12 × 64 × π
V = 768π  mm³

V = π·r²·h 
and D = 2·r => r = 16 : 2 = 8 mm

V = π·8²·12 = π·64·12 = 768 π mm³

Find the measures of:<br><br>all angles if 3(m∠1+m∠3) = m∠2+m∠4
slavikrds [6]

Answer:

Part 1) m∠1=45°

Part 2) m∠3=45°

Part 3) m∠2=135°

Part 4) m∠4=135°

Step-by-step explanation:

we know that

m∠1=m∠3 -----> by vertical angles Equation A

m∠2=m∠4 -----> by vertical angles Equation B

m∠1+m∠2=180° ----> by supplementary angles (linear pair) Equation C

3(m∠1+m∠3) = m∠2+m∠4 ----> Equation D

Substitute equation A and equation B in equation D

3(m∠1+m∠1) = m∠2+m∠2

6(m∠1) = 2m∠2

3(m∠1) =m∠2 -----> equation E

Substitute equation E in equation C and solve for m∠1

m∠1+3(m∠1)=180°

4(m∠1)=180°

m∠1=45°

<em>Find the measure of m∠3</em>

Remember that

m∠1=m∠3 (equation A)

therefore

m∠3=45°

<em>Find the measure of m∠2</em>

Remember that

m∠2=3(m∠1) (equation E)

substitute the value of m∠1

m∠2=3(45°)=135°

<em>Find the measure of m∠4</em>

Remember that

m∠2=m∠4 (equation B)

therefore

m∠4=135°

At maximum speed, an airplane tracked 1720 miles against the wind in 5 hours. Flying with the wind, the plane can travel the sam
nataly862011 [7]
Recall your d = rt, distance = rate * time.

as the plane goes against the wind, the plane is not really flying at "x" mph, but is really going slower, at " x - y ", because the wind is subtracting speed from it.

likewise, when the plane is going with the wind, is not really going at "x" mph, but at " x + y ", is going faster due to the wind, thus

\bf \begin{array}{lccclll}&#10;&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\&#10;&------&------&------\\&#10;\textit{against the wind}&1720&x-y&5\\&#10;\textit{with the wind}&1720&x+y&4&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;1720=(x-y)5\implies \frac{1720}{5}=x-y\\\\&#10;344=x-y\implies \boxed{y}=x-344\\&#10;---------------\\&#10;1720=(x+y)4\implies \frac{1720}{4}=x+y\\\\&#10;430=x+y\implies 430=x+\left( \boxed{x-344} \right)&#10;\end{cases}&#10;\\\\\\&#10;430=2x-344\implies 774=2x\implies \cfrac{774}{2}=x\implies 387=x

Solve photo question. Mathematics. Please. Easy one. And last one.
Elan Coil [88]
A collection of nickels and dimes is worth $4.40. There are 53 coins in all. How many nickels are there?

Nickel is a US coin worth 5 cents or 0.05.
Dime is a US coin worth 10 cents or 0.10

n + d = 53
0.05n + 0.10d = 4.40

n = 53 - d
0.05(53 - d) + 0.10d = 4.40  
2.65 - 0.05d + 0.10d = 4.40
0.05d = 4.40 - 2.65
0.05d = 1.75
d = 1.75 / 0.05
d = 35

n = 53 - d
n = 53 - 35
n = 18 

There are 18 nickels and 35 dimes.

0.05n + 0.10d = 4.40
0.05(18) + 0.10(35) = 4.40
0.90 + 3.5 = 4.40
4.40 = 4.40
