WebThe average diameter of pellets was measured by a photographic analysis method for 251 samples. This average diameter of each pellet was then used to calculate the mean diameter of the random sample for 251 pellets. The mean diameter was measured to be 13.54 ± 2.2 mm as shown in Figure 1. WebThe Curved surface area of the sphere = 4πr2. Now it is given in the question that the diameter of the sphere is decreased by 25% hence a new sphere is formed. Therefore, the diameter of the new sphere can be written as: = 2r - (25%) of (2r) = 2r - (25/100) × (2r) = 2r - (r/2) = 3r/2. Radius of the new sphere = 1/2 × 3r/2 = 3r/4.
