Introduction

When it comes to calculating the volume of a tube-shaped glass, we need to consider the shape and size of the glass. In this case, we are given the size of the base of the glass, which is 3.5 cm, and the height of the glass, which is 12 cm. We are also told that the water is only filled to a quarter of the glass. To find the volume of water in the glass, we need to use the formula for the volume of a cylinder, which is given by V = πr^2h, where r is the radius of the base and h is the height of the cylinder.

Calculating the Volume of the Glass

To calculate the volume of the glass, we need to first find the radius of the base. Since the size of the base is given as 3.5 cm, we can assume that the radius is half of the diameter, which is 3.5 cm. Therefore, the radius of the base is 3.5/2 = 1.75 cm.

Now, we can use the formula for the volume of a cylinder to find the volume of the glass. The formula is V = πr^2h, where r is the radius of the base and h is the height of the cylinder. Plugging in the values, we get:

V = π(1.75)^2(12) V = 22/7 * 3.0625 * 12 V = 113.125 cm^3

Calculating the Volume of Water in the Glass

Since the water is only filled to a quarter of the glass, we need to find a quarter of the volume of the glass. To do this, we can multiply the volume of the glass by 1/4.

Volume of water in the glass = 1/4 * 113.125 cm^3 Volume of water in the glass = 28.28125 cm^3

Conclusion

In conclusion, we have calculated the volume of a tube-shaped glass with a base of 3.5 cm and a height of 12 cm. We have also calculated the volume of water in the glass, assuming that the water is only filled to a quarter of the glass. The volume of the glass is 113.125 cm^3, and the volume of water in the glass is 28.28125 cm^3.
