Surface area and ordering rational numbers

Front

What is Surface Area?

Back

The total area that the surface of a three-dimensional object occupies.

Front

What is the formula for 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 the formula for the Lateral Surface Area of a Cylinder?

Back

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

Front

What is the Lateral Surface Area of a Prism?

Back

Lateral Surface Area = perimeter of the base × height.

Front

How do you calculate the Surface Area of a Rectangular Prism?

Back

Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is a rational number?

Back

A number that can be expressed as the quotient or fraction of two integers.

Front

How do you order rational numbers?

Back

By comparing their values, often by converting them to decimals or finding a common denominator.

Front

What is the relationship between percentages and fractions?

Back

A percentage is a fraction out of 100. For example, 25% = 25/100 = 1/4.

Front

What is the formula for the Surface Area of a Sphere?

Back

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

Front

What is the formula for the Volume of a Cylinder?

Back

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