Since A (area of circle = C) is given = 148 Where we assume: Y represents radius of the circle (r) X represents diameter of the circle (D) Pi (π) = 3.14 A = 2 * π * y 148 = 2 * 3.14 * y 148 = 6.28 * y y = 148/6.28 So, y = 23.56
D = 2 * y D = 2 * 23.56 So, D = 47.12
Assume A is unknown (not given as 148) A = π * y^2 A = 3.14 * (23.56)^2 A = 3.14 * 47.12 So, A = 147.95 (approx. A = 148)
