Question
A hemispherical bowl with an internal radius of 15 cm is
full of liquid. This liquid will be filled in cylindrical bottles with a radius of 5 cm and a height of 7 cm. How many bottles are required to empty the bowl? type-sscSolution
Given – the radius of the hemispherical bowl= 15cm The volume of the hemispherical bowl =2/3 πr3 =2/3×22/7×15×15×15 = (44×225×5)/7 Volume of hemispherical bowl= (44×225×5)/7 Now radius of cylindrical bottles = 5cm. and height =6cm So, the volume of cylindrical bottles = πr²h =22/7 ×25×6 Number of the bottles = (44×225×5)/7)/ (22/7 ×25×6) =15 Number of the bottles = 15
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.)...
Find the approximate value of Question mark(?). No need to find the exact value.
24.95 × (36.06 ÷ 6) + 74.95% of 159.89 – √(143.94) × 2....
(18.31)2 – (13.68)2 + (2344.20 + 82.32) ÷ ? = 229.90
32.12% of 2399.98 + 64.04% of 2499.95 = ? × 15.95
(21.02 × 5.83 × 12.03 ÷ 6.99 of 4.03) + 31.93% of 50.03 = ?
20.22% of (61.9 × 5.01) + 69.97 =?
29.81 % of 49.91 + 14.28% of 147.09 + 179.91 = ?3
?² × 55% of (29 + 32 - 41) = 41.66% of 216 + 9
? = 28.04² ÷ (4.01⁵ + 9.89 × 20.20) + 84.56% of (198.76 × 30.03)
(10.98% of 499.99) - 4.998 = √?
