Unit 7 Flashcard Practice

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

How do you calculate the volume of a pyramid?

Back

Volume = (1/3) × base area × height.

Front

What is the value of π (Pi) used in calculations?

Back

Approximately 3.14 or 22/7.

Front

If a cylinder has a height of 19 cm and a volume of 14,340.59 cm³, how do you find the radius?

Back

Rearrange the volume formula: r = √(V / (πh)).

Front

What is the volume of a cylinder with a radius of 7 in and height of 6 in?

Back

Volume = π(7²)(6) = 294π in³.

Front

How do you round a number to the nearest whole number?

Back

Look at the digit after the decimal: if it's 5 or more, round up; if it's less than 5, round down.

Front

What is the volume of a cylinder with a radius of 3 in and height of 4 in?

Back

Volume = π(3²)(4) = 36π in³.

Front

What is the volume of a cylinder with a radius of 5 cm and height of 10 cm?

Back

Volume = π(5²)(10) = 250π cm³.

Front

How do you convert cubic centimeters to cubic meters?

Back

Divide by 1,000,000 (1 m³ = 1,000,000 cm³).

Front

What is the volume of a cylinder with a radius of 4 in and height of 5 in?

Back

Volume = π(4²)(5) = 80π in³.
