What is the total surface area (in cm2) of a cone with a base radius of 28cm and height of 45 cm?\(\text{(use } \pi = \frac{22}{7}\text{)}\)
Arrange the ratios in ascending order \(5 : 3\tfrac{1}{3},\; 6\tfrac{1}{4} : 3\tfrac{1}{8} \text{ and } 3.5 : 4.5.\)
\(3.5 : 4.5 < 5 : 3\tfrac{1}{3} < 6\tfrac{1}{4} : 3\tfrac{1}{8}\)
\(6\tfrac{1}{4} : 3\tfrac{1}{8} < 5 : 3\tfrac{1}{3} < 3.5 : 4.5\)
\(5 : 3\tfrac{1}{3} < 3.5 : 4.5 < 6\tfrac{1}{4} : 3\tfrac{1}{8}\)
\(5 : 3\tfrac{1}{3} < 6\tfrac{1}{4} : 3\tfrac{1}{8} < 3.5 : 4.5\)
