Introduction

In mathematics, tables are used to represent data in a structured and organized manner. However, sometimes tables may have missing values that need to be calculated. In this article, we will focus on completing a table by calculating the missing values for the radius, base area, height, cylinder volume, and cone volume.

Understanding the Table

The table below represents the data for a cylinder and a cone.

Diameter (units)	Radius (units)	Base Area (sq. units)	Height (units)	Cylinder Volume (cubic units)	Cone Volume (cubic units)
10
20
30

Calculating the Radius

The radius of a circle is half of its diameter. Therefore, we can calculate the radius by dividing the diameter by 2.

Diameter (units)	Radius (units)
10	5
20	10
30	15

Calculating the Base Area

The base area of a circle is given by the formula A = πr^2, where A is the base area and r is the radius.

Diameter (units)	Radius (units)	Base Area (sq. units)
10	5	78.54
20	10	314.16
30	15	707.96

Calculating the Height

The height of a cylinder or a cone is not given in the table. However, we can assume that the height is the same for both the cylinder and the cone.

Diameter (units)	Radius (units)	Base Area (sq. units)
10	5	78.54
20	10	314.16
30	15	707.96

Calculating the Cylinder Volume

The volume of a cylinder is given by the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.

Diameter (units)	Radius (units)	Base Area (sq. units)
10	5	78.54
20	10	314.16
30	15	707.96

Calculating the Cone Volume

The volume of a cone is given by the formula V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.

Diameter (units)	Radius (units)	Base Area (sq. units)
10	5	78.54
20	10	314.16
30	15	707.96

Assuming a Height

Since the height is not given in the table, we will assume a height of 5 units for both the cylinder and the cone.

Diameter (units)	Radius (units)	Base Area (sq. units)	Height (units)	Cylinder Volume (cubic units)	Cone Volume (cubic units)
10	5	78.54	5	392.71	130.91
20	10	314.16	5	3141.6	1046.53
30	15	707.96	5	7079.6	2353.87

Conclusion

In this article, we calculated the missing values in a table for the radius, base area, height, cylinder volume, and cone volume. We used the formulas for the base area, cylinder volume, and cone volume to calculate the missing values. We also assumed a height of 5 units for both the cylinder and the cone. The completed table is shown above.
