A medicine capsule is in the shape of a cylinder with two hemispheres stuck to each of its ends (see Fig.). The length of the entire capsule is \(18 mm\) and the diameter of the capsule is \(7 mm\). Determine its surface area. (Take \(\pi=\frac{22}{7}\)).
Required area \(=\) \(mm^2\)
(Note: If the answer is a whole number, enter as it is. If not, enter the answer up to two decimal places)
