SSC CGL 2023 PYQ — Question 68

SSC CGL - 17 July 2023 - Shift 3 • Quantitative Aptitude • Q68

What is the radius of the circle that circumscribes the triangle ABC whose sides are 16, 30, and 34 units, respectively?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 17 units.

Dimension of the triangle = 16, 30, and 34

In △ABC

By Pythagoras theorem

⇒ AB2 = AC2 + BC2

⇒ 342 - 302 = AC2

⇒ AC2 = 1156 - 900

⇒ AC2 = 256 = 162

Hence, it is a right-angled triangle

The circumradius of a right-angled triangle = H/2 = 34/2 = 17 units
