Acircle has a radius of 10 centimeters. if 7/8 of the circle is cut away, what is the area of the remaining portion? use 3.14 for π. a) 44.86 cm2 b) 3.93 cm2 c) 39.25 cm2 d) 358.86 cm2 you : )

First let's calculate the area:

A=pi*R^2

And we will have:

A=3,14*100 => A=314

Now we need to know how much 7/8 of 314 is:

(87,5%) 7/8*314 = 274,75

The only thing left to do is the diference between the 2 values 314 (100%) and 274,75 (87,5%), wich will be:

314-274,75=39,25
