Calculate the missing length for this cylinder

Mathematics

QveST [7]3 years ago

For first cylinder Vloume = pi * r^2 * h 
where h is the height and r is the radius 
so by substitute
6908=pi * r^2 * 22
so r = 9.99 cm
For second cylinder Vloume<span> = pi * r^2 * h 
by substitute  
7884.54 = pi * r^2 * 31
so r = 8.99 
but the diameter is the required so 
d= 2*r = 2*8.99 
d= 17.99 cm</span>

I assume by the length you mean height so,

\frac{6908}{ \pi * 22^{2} } ≈ <span>4.54.

if you're supposed to round it, it'd be either 4.50, or 5

What equation relates the number of quarters x and the number of quarters x and the number of dime y to the goal of $10
Dimas [21]

1. Thom has a scale model of his car. The
MariettaO [177]

x =\frac{4}{3}inch is the size in wheels on the scale model .

<u>Step-by-step explanation:</u>

Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?

We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:

Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,

⇒ \frac{1}{12}  = \frac{x}{16}                 { x is size of wheel in scale model }

⇒ \frac{1(16)}{12}  = \frac{x}{16}(16)

⇒ x =\frac{16}{12}

⇒ x =\frac{4}{3}inch

Therefore , x =\frac{4}{3}inch is the size in wheels on the scale model .

Solve If QR = 6x + 1, PR = 14x - 13, and PQ = 5x - 2, find PR
solong [7]

Answer:

P____Q____R

PR= PQ+ QR

(14x-13) = (5x-2)+(6x+1)

14x-13= 11x – 1

14x – 11x = 13–1

3x = 12

x= 12/ 3

x= 4

PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5

If you want (PQ , QR ) this is the solution

PQ =5x-2=5(4)-2=20-2=18

QR =6x+1=6(4)+1=24+1=25

I hope I helped you^_^
