How can you cut apart and rearrange a circle to find the formula for its area? O A. Cut the circle in half and use the two straight edges to form two
sides of a square.
B. Cut the circle into slices and arrange them into triangles.
O C. Straighten out the outside edge of the circle and measure its
length.
D. Cut the circle into slices and arrange them into a parallelogram.

your answer   is c

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
