cm. How many bottles are required to empty the bowl?
type-ssc
Solution
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
