Deepali makes a model of a cylindrical kaleidoscope fo her science project. She uses a chart paper to make it. If the length of the kaleidoscope is 25 cm and radius 3.5 cm, the area of the paper she used, in square cm, is (pi = (22)/(7))

Find the area of the chart paper used to make the curved surface of a model of cylindrical kaleidoscope of length 25 cm and radius 3.5 cm

Amita wants to make rectangular cards measuring 8cm xx 5cm. She has a square chart paper of side 60cm. How many complete cards can she make from this chart? What area of the chart paper will be left?

Devika has a square piece of cloth of area 9m^(2) and she wants to make 16 square-shaped scarves of equal size out of it.What should possibly be the length of the side of the scarf that can be made out of this piece?

We wish to make a plano convex lens of focal length 16 cm from glass having refractive index 1.5. It is to be used in air. The radius of curvature of the curved surface is
