The probability that a train leaves on time is 0.9. The probability that the train arrives on time and leaves on time is 0.36. W

ASHA 777 [7]

P(arrives on time given leaves on time)=
P(B | A)= P(B n A) / P(A)
= P(A n B) / P(A)
= 0.36 / 0.9
= 0.4

The volume of a cylinder is

Dima020 [189]

The volume of a cylinder is equal to $\frac{1}{3}\pi r^{2} h$ , where r is the radius of the cylinder and h is its height.

324 = $\frac{1}{3}\pi r^{2} h$

324 = $\frac{1}{3}$ x 3.14 x $r^{2}$ x 1

309.55 = $r^{2}$

r = $\sqrt{309.55}$

r = approx. 17.59 inches

I hope this answer helped you! If you have any questions, feel free to ask away.
