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 one
A) 3.99 sq m  B) 3.34 sq m  C) 2.98 sq m  D) 2.98 sq m  E) 8.29 sq m
Area of the path = Area of the outer circle - Area 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   Answer:3.34 sq m
