Circumference of a quarter circle formula
WebWell, the formula for area of a circle is pi r squared, or r squared pi. So the radius is 3. So it's going to be 3 times 3, which is 9, times pi-- 9 pi. So we have 100 minus 9 pi is the area of the shaded region. And we got it right. Web1. Note that the radius is r = S Q = ( S R) 2 + ( S P) 2 = 8 2 + 6 2 = 100 = 10 by the Pythagorean theorem. Then, we know that the perimeter of a …
