Mathematics MCQs

Under the common school definition, a trapezium has one pair of parallel sides.
Parallelograms have two pairs.

Rectangle area is length multiplied by width.
Thus, 12 × 7 = 84 m².

Sphere volume is 4/3 πr³.
Thus, 4/3 × π × 27 = 36π cm³.

A standard deck has 26 red cards out of 52 total cards.
Thus, 26/52 = 1/2.

Range equals maximum minus minimum.
Thus, 40 - 12 = 28.

The sum is (n - 2) × 180°.
For n = 5, this is 3 × 180° = 540°.

Square area is side squared.
Thus, 9² = 81 cm².

The edge length is the cube root of the volume.
Since 6³ = 216, the edge is 6 cm.

There are 4 aces among 52 cards.
Thus, the probability is 4/52 = 1/13.

Matrix order is written as rows by columns.
Therefore, 3 rows and 4 columns give order 3 × 4.

The total interior angle sum is 720°.
Dividing by 6 equal angles gives 120°.

The side length is √144 = 12 cm.
The perimeter is 4 × 12 = 48 cm.
