Question

3 Coins of the same size (radius 1 cm) are placed on a table such that each of them touches the other two. The area enclosed by the coins is?

Answer 1

Area of each coin = πr²
                              = 22/7 x 1²
                               = 22/7 cm²
Area of three coins = 22/7 cm² x 3
                                = 9.42 cm²
