Question 551405
A chord of 48 cm is 7 cm from the center of a circle.
 Calculate the area of the circle.
:
we want to find r, or better yet r^2
:
the 7 cm line from the center bisects the chord, forms a right triangle where
one leg = 24 and the other leg = 7, the hypotenuse is the radius, therefore
r^2 = 24^2 + 7^2
r^2 = 576 + 49
r^2 = 625
:
Find area of the circle
A = {{{pi*625}}}
A = 1963.495 sq/cm
