A 25 cm wide path is to be made around a circular garden having a diameter of 4 meters. Approximate area of the path is square meters is?  Choose the correct choice from the following choices
A) 3.34 sq m B) 3.38 sq m C) 3.24 sq m D) 3.36 sq m E) 5.34 sq m
3.34 sq mrea of the path = 3.34 sq mrea of the outer circle - 3.34 sq mrea of the inner circle   = ∏{4/2 + 25/100}2 - ∏[4/2]2   = ∏[2.252 - 22] = ∏(0.25)(4.25) { (a2 - b2 = (a - b)(a + b) }   = (3.14)(1/4)(17/4)   = 53.38/16   = 3.34 sq m   3.34 sq mnswer:3.34 sq m
