a Wheel 15 inches in diameter is spun around 4 full turns. What distance,to the nearest inch, did a mark on the edge of the whee
lakkis [162]
If the wheel has a diameter of 15 inches, its radius is half that, or 7.5 inches then.

a full turn, or a full cycle around the wheel, namely around the circle is 360° or 2π radians.

now, in one turn or cycle, it covered an angle of 2π, in 2 cycles it covered 2(2π), in 3 it did 3(2π) and in 4 of course 4(2π).

so, what is the arc's length, whose radius is 7.5 and its central angle is 8π?

well.... you already know that s = rθ, therefore then, s = (7.5) (8π).

At dee dee's dinette the probability that a customer orders coffee is 0.60, the probability that a customer orders pie is 0.35,
Ulleksa [173]
For better understanding think of it this way. There are hundred customers, 60 orders coffee 35 orders pie and 30 does not order pie or coffee. 
This means that 70 does order coffee or pie or both. Out of those 70 people 10 will not order coffee and 35 will not order pie. Thus 70-10-35=25 will order both coffee and pie.
