Answer:

D) 45°

Step-by-step explanation:

I can’t see the triangle, but when you add up all the sides on a triangle it would equal 90°. So basically it would not be a, b, or c, because option A isn’t a degrees, option b doesn’t even make any sense, and option c, there are 3 sides to a triangle so then that leaves D being the correct answer.

A circle with area 36π has a sector with a central angle of 11/6π radians. What is the area of the sector?

bazaltina [42]

Answer:

33pi or 103.62 squre units

Step-by-step explanation:

$central \: angle \: ( \theta) \\ = \frac{11}{6} {\pi}^{c} = \frac{11}{6} \times 180 \degree = 330 \degree \\ \\ area \: of \: sector \\ = \frac{ \theta}{360 \degree} \times area \: of \: circle \\ \\ = \frac{ 330 \degree}{360 \degree} \times 36 \: \pi \\ \\ = \frac{ 330 }{10 } \pi \\ \\ = \red{ \bold{33\pi}} \: {units}^{2} \\ = 33 \times 3.14 \\ = 103.62 \: {units}^{2} \\$
