What is the probability of landing on a purple section if there are 3 purple sections out of 8 total sections?

Back

The probability is \( \frac{3}{8} \) which simplifies to \( \frac{1}{4} \).

Front

How would you classify an angle that measures less than 90 degrees?

Back

An angle that measures less than 90 degrees is classified as an Acute angle.

Front

What unit is used to measure volume?

Back

The unit used for volume is cubic feet (\( ft^3 \)).

Front

What is the formula for the area of a circle?

Back

The formula for the area of a circle is \( A = \pi r^2 \).

Front

If the radius of a circle is 50 cm, what is the area using \( \pi \approx 3.14 \)?

Back

The area is \( A = 3.14 \times 50^2 = 7850 \text{ cm}^2 \).

Front

What is the sum of the angles in a triangle?

Back

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

Front

If one angle in a triangle is 90 degrees and another is 52 degrees, what is the third angle?

Back

The third angle is \( 180 - 90 - 52 = 38 \) degrees.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.

Front

How do you calculate the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width: \( A = l \times w \).
