What is the area of a triangle with base 10 and height 6?
Answer: 30
Area of a triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30.
A right triangle has legs of length 5 and 12. What is the length of the hypotenuse?
Answer: 13
By the Pythagorean theorem, c² = 5² + 12² = 25 + 144 = 169, so c = 13.
What is the circumference of a circle with radius 7? (Use π ≈ 3.14)
Answer: 43.96
Circumference = 2πr = 2 × 3.14 × 7 = 43.96.
Two angles of a triangle measure 45° and 75°. What is the measure of the third angle?
Answer: 60°
The sum of angles in a triangle is 180°, so the third angle = 180° − 45° − 75° = 60°.
What is the area of a circle with diameter 10? (Use π ≈ 3.14)
Answer: 78.5
Radius = 5, so area = πr² = 3.14 × 25 = 78.5.
A rectangle has a length of 9 and a width of 4. What is its perimeter?
Answer: 26
Perimeter = 2(length + width) = 2(9 + 4) = 2 × 13 = 26.
What is the volume of a rectangular prism with length 5, width 3, and height 4?
Answer: 60
Volume = length × width × height = 5 × 3 × 4 = 60.
