Question

In circle J, m/KJL = 160° and the area of the shaded sector = 367. Find the length of JK.

Answer 1

hello

the answer to the question is:

length of JK = length of JL = r or radius

`A \: = (θ)/(360) * \pi {r}^(2) \\ 36\pi \: = (160)/(360) * \pi {r}^(2) \\ {r}^(2) = 81 \: - > r = jk \: = 9`
