2nd and 4th last test

Front

What is the formula for the volume of a sphere?

Back

Volume = (4/3) × π × r³, where r is the radius.

Front

How do you calculate the volume of a cylinder?

Back

Volume = π × r² × h, where r is the radius and h is the height.

Front

What is the volume of a hemisphere?

Back

Volume = (2/3) × π × r³, where r is the radius.

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3) × π × r² × h, where r is the radius and h is the height.

Front

What is the difference between radius and diameter?

Back

Radius is half the diameter; Diameter = 2 × Radius.

Front

If the radius of a sphere is 5 m, what is its volume using π = 3.14?

Back

Volume = (4/3) × 3.14 × (5)³ = 523.3 m³.

Front

If the radius of a cylinder is 7 m and height is 10 m, what is its volume using π = 3.14?

Back

Volume = 3.14 × (7)² × 10 = 1540 m³.

Front

How do you round numbers to the nearest tenth?

Back

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

Front

What is the volume of a cone with a radius of 3 m and height of 9 m?

Back

Volume = (1/3) × 3.14 × (3)² × 9 = 28.3 m³.

Front

What is the volume of a hemisphere with a radius of 4 in?

Back

Volume = (2/3) × 3.14 × (4)³ = 33.5 in³.
