yes it can
An arc
1/6 because OOOOOO
The answer depends on the number whose fraction you are trying to find.
The question cannot be answered because a number of key items of information are missing:A decimal fraction representing which quantity?How large are the circles?How large is the square?
Concentric circles have the same center. They are not necessarily the same size. If two concentric circles have the same area, then they are congruent, meaning they coincide when superimposed.
The derivative of a circles area is it's circumference.
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
-6
Area of any circle = pi*radius2
nope a portion of a circles area is a triangle
pi (r^2)
Using 3.14 as Pi the area of circle is: 0
