This means that it sweeps out half of the circle so that the chord is actually going across the whole diameter of the circle. So if the chord is going across the diameter and has a length of 15 inches, then the radius of the circle should be 7.5 inches. read more at: https://www.ck12.org/trigonometry/Length-of-a-Chord/lesson/Length-of-a-Chord-TRIG/
Formula for the area of a circle: A = pi x r^2
Solve for the radius:
36pi = pi x r^2
r^2 = 36
r = 6 cm
Hope this helps! :)
Answer:
the answer to (8.4 × 102) (2.5 × 106) = 227,052
2 would be the answer. Replace the x with the three and multiply that with the 2 and then subtract 4.
