Unit 7 Test Review

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

How do you calculate the lateral surface area of a cylinder using π = 3.14?

Back

Lateral Surface Area = 2 * 3.14 * r * h.

Front

What is the formula for the total surface area of a prism?

Back

Total Surface Area = 2 * Base Area + Lateral Surface Area.

Front

How do you find the volume of a cylinder?

Back

Volume = πr²h.

Front

What is the formula for the volume of a sphere?

Back

Volume = (4/3)πr³.

Front

How do you calculate the volume of a sphere using π = 3.14?

Back

Volume = (4/3) * 3.14 * r³.

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area does not include the area of the bases, while total surface area includes both the lateral area and the area of the bases.

Front

What is the significance of rounding in surface area and volume calculations?

Back

Rounding helps to provide a more manageable number, especially when dealing with measurements.

Front

How do you round a number to the nearest tenth?

Back

Look at the hundredths place; if it's 5 or more, round up.

Front

What is the formula for the area of a circle?

Back

Area = πr².
