a steel tube has an outside diameter of 15 cm, an inside diameter of 13 cm, and is 3.7 m long. The volume of the steel contained in the tube in cubic cm is ?

V= pi*r^2*h
V= pi*7.5cm^2*370cm
V= pi*56.25cm*370cm
V= 65384.397

V= pi*r^2*h
V= pi*6.5cm^2*370cm
V= pi*42.25cm*370cm
V= 49110.947

65384.397- 49110.947 = 16273.45
V= 16273.45

Oh boy, we're talking about steel tubes now? Talk about a pipe dream! Alright, let's do some math. To find the volume of the steel contained in the tube, we need to subtract the volume of the hollow part from the total volume.

First, let's find the volume of the whole tube. We can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height. Since we're given the diameter, we need to halve it to get the radius. The outside radius is 15 cm / 2 = 7.5 cm, and the inside radius is 13 cm / 2 = 6.5 cm.

Now, we calculate the volume of the whole tube:
V_whole = π(7.5^2)(3.7) cm^3.

Next, we need to find the volume of the hollow part. We can use the same formula for a cylinder, but this time, we'll use the inside radius:
V_hollow = π(6.5^2)(3.7) cm^3.

Finally, we subtract the volume of the hollow part from the volume of the whole tube to find the volume of the steel:
V_steel = V_whole - V_hollow cm^3.

Go ahead, calculate that and let me know what you get!

To find the volume of the steel contained in the tube, we need to find the volume of the outer cylinder and subtract the volume of the inner cylinder.

Step 1: Calculate the volume of the outer cylinder.
The formula to calculate the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.

The radius of the outer cylinder is half the outside diameter, so r = 15 cm / 2 = 7.5 cm.

The height of the outer cylinder is given as 3.7 m, which is equivalent to 370 cm.

Using the formula V = πr^2h, we can calculate the volume of the outer cylinder:
V_outer = π × (7.5 cm)^2 × 370 cm

Step 2: Calculate the volume of the inner cylinder.
Using the same formula V = πr^2h, the radius of the inner cylinder is half the inner diameter, so r = 13 cm / 2 = 6.5 cm.

The height of the inner cylinder is also 370 cm.

Using the formula V = πr^2h, we can calculate the volume of the inner cylinder:
V_inner = π × (6.5 cm)^2 × 370 cm

Step 3: Subtract the volume of the inner cylinder from the volume of the outer cylinder.
V_steel = V_outer - V_inner

Finally, we can plug in the values and calculate the volume of the steel contained in the tube:
V_steel = (π × (7.5 cm)^2 × 370 cm) - (π × (6.5 cm)^2 × 370 cm)

To find the volume of the steel contained in the tube, we need to find the volume of the entire cylinder and subtract the volume of the hollow part.

Step 1: Find the volume of the entire cylinder
The formula for the volume of a cylinder is given by V = πr^2h, where r is the radius and h is the height (or length) of the cylinder.

Given:
Outside diameter (d) = 15 cm
Outside radius (r1) = d/2 = 15/2 = 7.5 cm

Length (h) = 3.7 m = 370 cm

Calculate the volume of the entire cylinder:
V1 = πr1^2h

Step 2: Find the volume of the hollow part
Similarly, we can find the volume of the hollow part, which is the space between the outer and inner diameters.

Inner radius (r2) = 13/2 = 6.5 cm

The volume of the hollow part is the difference between the volume of the cylinder with the outer radius and the cylinder with the inner radius.
V2 = πr1^2h - πr2^2h

Step 3: Find the volume of the steel contained in the tube
Finally, to find the volume of the steel contained in the tube, we subtract the volume of the hollow part from the volume of the entire cylinder.
Volume of steel = V1 - V2

Let's do the calculations:

V1 = π(7.5 cm)^2 * 370 cm
V2 = π(7.5 cm)^2 * 370 cm - π(6.5 cm)^2 * 370 cm

Now we can substitute the values and calculate the answer:
Volume of steel = V1 - V2

I'll calculate the final answer to find the volume of the steel contained in the tube in cubic cm.
