A circle has radius x cm. What is the area of a sector of the circle with angle 135°, leaving the answer in terms of x and π?
A
\( \frac{\pi x^2}{8} \)
B
\( \frac{3\pi x^2}{8} \)
C
\( \frac{5\pi x^2}{8} \)
D
\( \frac{3\pi x}{8} \)
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
A = θ 360 x πr2 = 135 360 x π x x2 = (3πx2)/8
