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

Back

In calculations, π is often approximated as 3.14.

Front

If a sphere has a diameter of 10 inches, what is its radius?

Back

The radius r is half of the diameter, so r = 10 inches / 2 = 5 inches.

What is the relationship between diameter and radius?

Back

The diameter d of a sphere is twice the radius: d = 2r.

Front

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

Back

To round a number to the nearest whole number, look at the digit to the right of the decimal point. If it's 5 or more, round up; if it's less than 5, round down.
