Direction: Each of the questions below consists of two statements numbered I and II given below it. You are to decide whether the data provided in the statements are sufficient to answer the questions. Read both statements and give the answer
-
What is the perimeter of a semi-circle ?
I. The radius of the semi- circle is equal to half the side of a square.
II. The area of the square is 196 sq cm.
-
- If the data in Statement I alone are sufficient to answer the question while the data in Statement II alone are not sufficient to answer the question
- If the data in Statement II alone are sufficient to answer the question while the data in Statement I alone are not sufficient to answer the question
- If the data in Statement I alone or in Statement II alone are sufficient to answer the question
- if the data in both the Statement I and II are not sufficient to answer the question
- If the data in both the Statements I and II together are necessary to answer the question
Correct Option: E
From Statement II.
Suppose, side of a square be x.
Hence, x2 = 196
∴ x = 14 cm
From Statements I and II,
Radius of semi-circle, r = 7 cm
∴ Circumference of semi-circle
πr = 22/7 x 7 = 22 cm
Hence, both Statement are required .
