Front

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

Front

Calculate the volume of a cylinder with height 10 cm and radius 3 cm.

Back

The volume is approximately 283 cm³.

Front

What are complementary angles?

Back

Complementary angles are two angles that add up to 90°.

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to 180°.

Front

What is the measure of a right angle?

Back

A right angle measures 90°.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a shape.

Front

Dilate the point (3, 4) by a scale factor of 1/2.

Back

The new point is (1.5, 2).

Front

What is the sum of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180°.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90°.
