Front

What is the value of pi used in calculations?

Back

Pi (π) is approximately 3.14.

Front

How do you round a number to the nearest hundredth?

Back

Look at the third decimal place: if it's 5 or more, round up the second decimal place by one; if it's less than 5, keep the second decimal place the same.

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where r is the radius of the sphere.

Front

How do you find the volume of a cylinder?

Back

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

Front

What is the formula for the surface area of a sphere?

Back

A = 4πr², where r is the radius.

Front

What is the difference between volume and surface area?

Back

Volume measures the space inside a 3D object, while surface area measures the total area of the object's outer surface.

Front

How do you calculate the surface area of a cylinder?

Back

A = 2πrh + 2πr², where r is the radius and h is the height.

Front

What is the unit for measuring volume?

Back

Common units for volume include cubic centimeters (cm³), cubic meters (m³), and liters.

Front

What does 'squared' mean in measurements?

Back

'Squared' refers to a measurement of area, calculated as length × width, and is expressed in square units (e.g., cm²).

Front

What does 'cubed' mean in measurements?

Back

'Cubed' refers to a measurement of volume, calculated as length × width × height, and is expressed in cubic units (e.g., cm³).
