Question

In a triangle ABC, if b = 2, B = 30⁰ then the area of circumcircle of triangle ABC in square units is –

• A. p
• B. 2p
• C. 4p
• D. 6p

Answer 1

Answer: (C)

4p

Answer 2

R = $\frac { \mathrm { b } } { 2 \sin \theta } = \frac { 2 } { 2 \sin 30 ^ { \circ } }$ = 2

Area of circle = pR² = 4p
