Question

Angle DCA is 120°. What percent of the circle's area does this section represent?

A) 23%
B) 27%
C) 33%
D) 67%

Answer 1

a circle is 360

so we're going to set up a proportion

120 x
------ = ------
360 100

then cross multiply and divide

120 times 100=12000/360=33.3333333

so the answer is C. 33
