The volume of a cylinder with radius 5 cm and height 10 cm is closest to:
Answer: 785 cm³
V = πr²h = π × 25 × 10 ≈ 785 cm³.
How many vertices does a square pyramid have?
Answer: 5
A square pyramid has 4 base vertices plus 1 apex, totaling 5 vertices.
What is the lateral surface area of a cone with radius 3 cm and slant height 7 cm?
Answer: 21π cm²
Lateral surface area of a cone = πrl = π × 3 × 7 = 21π cm².
A sphere has a radius of 6 cm. What is its volume?
Answer: 288π cm³
V = (4/3)πr³ = (4/3)π × 216 = 288π cm³.
