What is a Pythagorean triple?

Back

Front

Identify a Pythagorean triple from the following: 3, 4, 5; 5, 12, 13; 8, 15, 17; 22, 27, 35.

Back

The set 22, 27, 35 is NOT a Pythagorean triple.

Front

What is the height of a cone if the radius is 3 m and the slant height is 7 m?

Back

Front

What is the diameter of a cone if the radius is 6 cm?

Back

The diameter (d) is twice the radius: d = 2 * r = 2 * 6 cm = 12 cm.

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.

Front

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

Back

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

Front

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

Back

In calculations, π is often approximated as 3.14.

Front

If a cone has a height of 8 cm and a diameter of 12 cm, what is the slant height?

Back

The slant height is 10 cm.
