Question
A solid cone is placed inside a solid hemisphere, both
having the same radius and height. If the volume of the cone is 150 cm³, find the total volume of the cone and the hemisphere combined.Solution
Volume of the cone = (1/3)πr²h, Volume of the hemisphere = (2/3)πr³, Given: Volume of the cone = 150 cm³. Volume of the hemisphere = 2 × Volume of the cone Volume of the hemisphere = 2 × 150 = 300 cm³. Total volume = Volume of the cone + Volume of the hemisphere Total volume = 150 + 300 = 450 cm³. Correct option: D) 450 cm³
?2/3 = 33.33% of 107.99 + 45.45
[54.96 × √99.96 – {(25.02/6.84)% of 280.24}]/(3.032 × 19.87) = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
45.22 of 499.98% + 399.99 ÷ 20.18 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(20.23% of 780.31) + ? + (29.87% of 89.87) = 283
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
- 27.99² - 40.02% of 419.99 + √3135.99 = ? X 5.99
3.934 - 124.07 + 35.94 + 12.83 of 4.85 - 84.76 ÷ √26 = ?3Â
