3^2 -[3*2^2-{(5*2^2-7)^2/13+12/(3*2^3-2 ^2-3)]/2}^2/17^2

pls refer ro the top for answer

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
