Multiply 3200 * 0.045
144 * 8=1152
The answer is HJ , just got 100 on the quiz :)
The formula of the area of the circle is
Area = pi * (d/2)^2
So using the formula,
Area = 3.14 * (30/2)^2
Area = 3.14 * 15^2
Area = 706.5 ft^2
So the area of the hockey rink is 706.5 ft^2
The total number of fish available in the tank is (18 + 22) = 40. We want to randomly select 2 fish and come up with 2 goldfish. The probability for 1 goldfish to be taken out would be 18/40.
Now, after drawing the first fish, the probability to get another goldfish would be 17/39. And the probability to draw 2 goldfish would be the product of both probabilities.
P = (18/40)(17/39) = 51/260
Thus, the answer is <span>B.</span>
