What Is The Volume Of A Cylinder, In Cubic Meters, With A Height Of 5 M And A Base Diameter Of 20 M? Round To The Nearest Tenth.
Understanding the Basics of a Cylinder
A cylinder is a three-dimensional shape with two parallel and circular bases connected by a curved lateral surface. The volume of a cylinder is a fundamental concept in mathematics, and it's essential to understand how to calculate it. In this article, we'll explore the formula for calculating the volume of a cylinder and apply it to a real-world scenario.
The Formula for the Volume of a Cylinder
The formula for the volume of a cylinder is given by:
V = πr²h
Where:
- V is the volume of the cylinder
- π (pi) is a mathematical constant approximately equal to 3.14
- r is the radius of the base of the cylinder
- h is the height of the cylinder
Calculating the Volume of a Cylinder with a Given Height and Base Diameter
Now, let's apply the formula to calculate the volume of a cylinder with a height of 5 m and a base diameter of 20 m. To do this, we need to find the radius of the base.
The radius of the base is half of the diameter
So, the radius of the base is:
r = 20 m / 2 = 10 m
Now, we can plug in the values into the formula:
V = π(10 m)²(5 m)
V = 3.14 × 100 m² × 5 m
V = 1570 m³
Rounding to the Nearest Tenth
The calculated volume is 1570 m³. However, we need to round it to the nearest tenth. To do this, we'll look at the hundredth place, which is 0 in this case. Since the hundredth place is 0, we can round the volume to 1570.0 m³.
Conclusion
In this article, we've explored the formula for calculating the volume of a cylinder and applied it to a real-world scenario. We've calculated the volume of a cylinder with a height of 5 m and a base diameter of 20 m, and rounded it to the nearest tenth. The calculated volume is 1570.0 m³.
