FLASHCARD QUESTION

Front

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

Back

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

2.

FLASHCARD QUESTION

Front

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

Back

Total Surface Area (SA) = 2πrh + 2πr², where r is the radius and h is the height.

3.

FLASHCARD QUESTION

Front

If a cylinder has a radius of 3 cm and a height of 5 cm, what is its lateral surface area?

Back

Lateral Surface Area = 2π(3)(5) = 30π ≈ 94.25 cm².

4.

FLASHCARD QUESTION

Front

What is the volume formula for a cylinder?

Back

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

5.

FLASHCARD QUESTION

Front

How do you find the radius if you know the diameter of a cylinder?

Back

Radius (r) = Diameter (d) / 2.

6.

FLASHCARD QUESTION

Front

What is the relationship between the radius and diameter of a cylinder?

Back

The diameter is twice the radius: Diameter (d) = 2 × Radius (r).

7.

FLASHCARD QUESTION

Front

If a cylinder has a height of 10 cm and a radius of 4 cm, what is its total surface area?

Back

Total Surface Area = 2π(4)(10) + 2π(4)² = 80π + 32π = 112π ≈ 351.86 cm².
