if a cylinder has a volume of approximately 125.6 cubic cm and has a height of 10cm what is the length of the radius
Elina [12.6K]

Answer:

radius = 4 cm

Step-by-step explanation:

To find the length of the radius, we will follow the step below;

First, write down the formula for finding the volume of a cylinder

v=πr²h

where v is the volume of a cylinder

r is the radius      and

h is the height of the cylinder

from the question given,

v=125.6    and h = 10 cm

we can now proceed to insert the values into the formula and solve for r

note that π is a constant which is equal to 3.14

v=πr²h

125.6 =3.14×r×10

125.6 =31.4 r

Divide both-side of the equation by 31.4

125.6/31.4 =31.4 r/31.4

4 = r

r =4 cm

The length of the radius = 4 cm

Need help same math paper but the back now I hope your able to read it cleary I need help with hw
vovikov84 [41]

Answers:

4) r = √[V/(πh)]; d ≈ 5 in

5) 1.25x + 2.50y = 25.00 ; 11 combinations

Step-by-step explanation:

4) (a) Formula for radius

V = πr²h     Divide each side by πh

V/(πh) = r²     Take the square root of each side.

r = √[V/(πh)]

(b) Diameter of tuna can

(i) <em>Data: </em>

V = 66 in³

h = 3.3 in

(ii) <em>Calculations </em>

r = √[V/(πh)]

  = √[66/(π × 3.3)]

  = √(20/π)

  = 2√(5/π)

d = 2r

  = 4√(5/π)

  ≈ 5 in

5) Hot dogs and hamburgers

(a) <em>The equation </em>

Let x = the number of hot dogs

and y = the number of hamburgers

Then

1.25x + 250y + 7 × 0.50 = 28.50

     1.25x + 250y + 3.50 = 28.50     Subtract 3.50 from each side

                1.25x + 2.50y = 25.00

(b) <em>Plot the graph</em>

 Let x = 0. Then

2.50y = 25.00     Divide each side by 2.50

       y = 10

Plot a point at (0, 10).

Let y = 0. Then,

1.25x = 25.00     Divide each side by 1.25

       x = 20

Plot a point at (20, 0).

Draw a straight line between the two points.

Your graph should look like the one below.

(c) <em>Hot dog/hamburger combinations </em>

The possible hot dog/hamburger (x/y) combinations are:

0x + 10y, 2x + 9y, 4x + 8y, 6x + 7y, 8x + 6y, 10x + 5y, 12x + 4y, 14x + 3y, 16x + 2y, 18x + 1y, 20x + 0y

Thus, there are 11 different combinations that Zeke and his friends can buy for $28.50.

It works like this, because one hamburger costs $2,50 and a hamburger half as much.

You can replace one hamburger with two hot dogs (or vice versa) and still spend the  same amount of money,.
