Area of a circle "ds" over the whole circle formula_33 is just the arc length, which is its circumference, so this shows that the area "A" enclosed by the circle is equal to formula_34 times the circumference of the circle. Note that the area of a semicircle of radius r can be computed by the integral formula_35. By trigonometric substitution, we substitute formula_36, hence formula_37 The last step follows since the trigonometric identity formula_42 implies that formula_43 and formula_44 have equal integrals over the interval formula_45, using integration by substitution. But on the other hand, since formula_46, the sum of the two integrals is
Straight Out of Line Straight Out of Line "Straight Out of Line" is the lead single from Godsmack's third studio album "Faceless". After its release, the song immediately ascended to number one on the Mainstream Rock chart, and hit the top 10 on the Modern Rock chart.
