Sample Questions

1multiple correct

Which of the following are correct formulas for a cone? (Select all correct options)

Show answer

Curved surface area = πrl, Volume = (1/3)πr²h, Total surface area = πr(l + r), Base area = πr²

All formulas are correct except slant height formula. The correct formula is l² = h² + r², not l = h² + r².

2multiple choice

A hemisphere has radius 3 cm. Its curved surface area is:

Show answer

18π cm²

Curved surface area of hemisphere = 2πr² = 2π × 3² = 2π × 9 = 18π cm²

3multiple choice

The volume of a sphere with radius 3 cm is:

Show answer

36π cm³

Volume of sphere = (4/3)πr³ = (4/3)π × 3³ = (4/3)π × 27 = 36π cm³

4multiple choice

A solid hemisphere has radius 4 cm. Its total surface area is:

Show answer

48π cm²

Total surface area of solid hemisphere = 2πr² + πr² = 3πr² = 3π × 4² = 3π × 16 = 48π cm²
