An interior decorator is recycling some old lampshades by covering them inmodern fabrics. The lampshades consist of two circular hoops of radii r and R joined by straight shuts of length L as shown in the diagram below. The area of fabric, A, needed to cover eachlampshade can be calculted using the formula: A = 3.1402 + 101. Where r, R and L are measured in centimeu-es(cm), and A is measured in square centimetres (cmz). a) What area of fabric would be needed to cover a lampshade with hoops of (1 mark)radii 15 cm and 22 cm and struts of length 0.51 m? Give your answer to thenearest square centimetre.
