Find the level of water in the flask. The radius of the base of a conical flask r = 10.5 c m. The volume of water in the conical flask V = 924 c. c. = 924 c m 3. WebJan 2, 2024 · Step 1: Take a hollow right-circular cone of a known height h and base radius r. Also, take a hollow right-circular cylinder of the same height h and base radius r such that it is open at the top and closed at the bottom. Step 2: Fill the cone with salt up to the brim, as shown in Figure 40.2. Pour the entire quantity of salt from the cylinder.

WebOct 20, 2024 · 1 Answer Sorted by: 1 Ratio of radius to the height of the cone = R H = 1 2 and this remains same at all height. Now at a given height h, r = h 2 So, V = π 3 r 2 h = π … WebApr 7, 2024 · Let us assume that 'h' is the height of a curved surface. We know that the formula for the area of a circle is πr². By adding these two, we will get the formula of the cylinder. The volume of cylinder = πr²h. Where r - radius of the circle. Hence the product of height with the area of the circle gives the volume of the cylinder. lobulated contour meaning
