Volume, surface Area , Two-way tables & Matrices Test

Front

What is the formula for the volume of a hemisphere?

Back

Volume = (2/3)πr³, where r is the radius.

Front

How do you calculate the total surface area of a cylinder?

Back

Total Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of variables.

Front

How do you find the percent of a group?

Back

Percent = (part/whole) × 100.

Front

What is the formula for the lateral area of a cylinder?

Back

Lateral Area = 2πrh, where r is the radius and h is the height.

Front

What is the difference between volume and surface area?

Back

Volume measures the space inside a 3D object, while surface area measures the total area of the object's surface.

Front

How do you interpret data from a two-way table?

Back

You analyze the relationship between two categorical variables by examining the frequencies in the table.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What is a matrix in mathematics?

Back

A matrix is a rectangular array of numbers arranged in rows and columns.

Front

How do you calculate the surface area of a sphere?

Back

Surface Area = 4πr², where r is the radius.
