Since the ratio of the radius is 3 to 5 let's make them 3x and 5x
(5x^2-3x^2)pi=32
2x^2*pi=32
2x^2=10.18.....didnt round yet
x^2=5.0929...
Now 5x^2*pi=80
In Jennifer's bag, there are 7 marbles. Out of 7 marbles, 4 of them are blue.
Hence, the probability that Jennifer picks one blue marble is 4/7. (Option 1).
Answer: 5 + 5^2 + 5^3 + 5^4
Explanation:
1) First time, when Kris forwards the e-mail it reaches other 5 people.
2) Second time, each one of the 5 people forawer to other 5 people, meaning that the second time the e-mail has reached other 5^2 people.
3) Third time, each 5^2 people forwarded to other 5 people, so the email reaches other 5^3 people
4) Fourth time => 5^4 new people.
So, the total number (not including Kris) is 5 + 5^2 + 5^3 + 5^4.
