The area of a circle is A = r^2pi Since the area is equal to 121pi the equation would be, 121pi = r^2. To find r in terms of pi take the square root of 121, to find the radius. Then multiply that by two to get the diameter.
One way to illustrate the binomial<span> distribution is with a histogram. A histogram shows the possible values of a probability distribution as a series of vertical bars.</span>
