Question

Find the area of a 60 degree sector of a circle that has a 5-inch radius.

Answer 1

4.16π

Keys:

`Sigma(\sigma) = radius\\Theta(\theta) = angle`

Explanation:

`\sigma = 5\\A = (\theta)/(360^\circ) * \pi \sigma^2\\A = (60^\circ)/((360^\circ)/(6) ) * \pi (5)^2\\A = (25)/(6) \pi \\A= 4.16\pi`
