Find the area of a circle with radius 5 cm. (Use π = 3.14)

78.5 cm² 

Solution: Use the formula for circle area with given radius.  πr² = 3.14 × 5² = 3.14 × 25 = 78.5 cm² 

300

Factor the expression: x² - 9

(x+3)(x-3)

Solution: Recognize this as a difference of squares.

300

Calculate the median of the dataset: 3, 7, 8, 9, 11, 15

Solution: Order numbers, select middle value.

300

How many milliliters are in 2.5 liters?

2500 milliliters 

Solution: 1 L = 1000 mL, so 2.5 L = 2500 mL.

400

What is the value of 2³ + 4² - 3¹?

 21 

Solution: Calculate each exponent, then perform addition and subtraction.

400

What is the volume of a rectangular prism with length 4 cm, width 3 cm, and height 5 cm?

60 cm³ 

Solution: Apply the formula for rectangular prism volume. Volume = length × width × height = 4 × 3 × 5 = 60 cm³

500

In a right triangle, if one angle is 30°, what are the other two angles?

The other angles are 60° and 90° 

Solution: In a right triangle, one angle is always 90°. The sum of angles in a triangle is 180°, so 180° - 90° - 30° = 60°.

500

Find the equation of a line passing through points (2, 3) and (4, 7)

y - 3 = 2(x - 2) or y = 2x - 1 

Solution: Use point-slope form or slope-intercept form.
