The angle of a sector is $\frac{\pi}{4}$ radians, and the radius of the circle is 8 cm. What is the area of the sector?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. $8\pi$ cm².

Area of sector = $1\over2$ r²θ

⇒ $1\over2$ × (8)² × $π\over4$ = $1\over2$ × 64 × $π\over4$ = 8π cm²
