So the formula for the area of the circle is
. To find the radius is divide the diameters by 2, which in this case its 2 and 3. Now we can find the areas.
Now just subtract the areas:
The difference in areas is 5 pi, or 15.71.
Answer:
0.05 or 1/20
Step-by-step explanation:
Since there are 5 people, you need to divide 1/4 by 5.
1/4 can also be written as 0.25.
0.25 / 5 = 0.05
So, each friend will get 0.05 or 1/20!
7.5 %
Step-by-step explanation:
We by finding how far from the mean the 999 volume caps are, using z score;
Z = (x – μ) / σ
Z = (999 – 998) / 7
Z = 0.143
We use the z-table to find the confidence levels;
= 85%
= 0.85
Since we are finding proportion of bottles have volumes greater than 999
mL;
1 – .85 = .15
0.15/2 = 0.075
= 7.5%
