The answer would be 153.86... First of all let's establish the formula to work out the area if a circle - it's area = pi * (radius * radius)... Then let's substitute the values... So we know that the diameter is 14 inches so that must mean the radius is 7 inches, since the radius is simply half of the diameter... Then we multiply pi (I am using 3.14) with 49 inches (since 7 * 7 = 49)... Then the answer you get is 153.86

Question
Solve the following system of inequalities graphically : x + y > 4, 2x - y > 0
Answer:
The y intercept is -1
Step-by-step explanation:
y-14=6(x-2.5)
We need to get the equation in the form y = mx+b where b is the y intercept
Distribut the 6
y-14 = 6x -15
Add 14 to each side
y-14+14 = 6x-15+14
y = 6x-1
The y - intercept is -1
No offense to the person above me but they are wrong. So first you have to examine the probability of the first card being blue. Since there are 20 total cards, and three are blue, the probability of the first card being blue is 3 out of 20 or 3/20. Now examine the probability of the second card being blue. Since the previous card was replaced, the total number of cards is still 20. Three out of 20 cards are blue (just like before), so the probability of the second card being blue is 3/20. But the answer is NOT 3/20. Because you have to multiply the two probabilities together because it is happening back to back (if that makes sense). So multiply the two fractions. 3/20 times 3/20 = 9/400. So your ANSWER IS 9/400. (I just put it in caps so it’s easy to see) The fraction can’t be simplified any further. Hope this helps!
