Answer: He would need to ride on average 7.9 miles each day
Step-by-step explanation:
let x = the average number of miles he would have to ride each day to reach his goal.

No it should be a 50% chance because the first roll is a independent variable, 6/12=1/2
The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
