If radius is (14) cm and central angle is ( \frac{5\pi}{7} ) radians, what is the area of the sector?

Question

Answer and explanation

Correct answer: (70\pi) square cm

Area is ( \frac{1}{2}r^2\theta=\frac{1}{2}\times196\times\frac{5\pi}{7}=70\pi ). Use this formula directly with a radian angle.
