Question
Find the area of a circle. Statement I: The
radius of a circle is one-third of the area of the rectangle. Statement II: Area of rectangle is 210 cm2. For each of the following questions statements I and II are given. Use the data of those statements and then determine which of the following statements is necessary to answer the question:Solution
Statement I & II: Radius of circle = (1/3) × 210 = 70 cm Area of circle = πr2 = (22/7) × 70 × 70 = 15400 cm2 Therefore both the statements are required to answer the question.
