How many inches are in 4.5 feet?
Answer: 54 inches
1 foot = 12 inches, so 4.5 × 12 = 54 inches.
What is the area of a circle with a radius of 6 feet? (Use π ≈ 3.14)
Answer: 113.04 sq ft
Area = π × r² = 3.14 × 6² = 3.14 × 36 = 113.04 sq ft.
A rectangle has a length of 12 ft and a width of 5 ft. What is the length of its diagonal?
Answer: 13 ft
Diagonal = √(12² + 5²) = √(144 + 25) = √169 = 13 ft.
What is the surface area of a cube with a side length of 4 feet?
Answer: 96 sq ft
Surface area of a cube = 6 × side² = 6 × 16 = 96 sq ft.
The sum of the interior angles of any triangle always equals:
Answer: 180°
The three interior angles of any triangle always sum to exactly 180°.
What is the volume of a cylinder with radius 3 ft and height 7 ft? (Use π ≈ 3.14)
Answer: 197.82 cu ft
Volume = π × r² × h = 3.14 × 9 × 7 = 197.82 cu ft.
