What is the area of a triangle with a base of 10 m and a height of 6 m?
Answer: 30 m²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 m².
A circle has a radius of 7 cm. What is its approximate area? (Use π ≈ 3.14)
Answer: 153.86 cm²
Area = π × r² = 3.14 × 7² = 3.14 × 49 ≈ 153.86 cm².
Two angles are supplementary. One angle measures 65°. What is the measure of the other angle?
Answer: 115°
