9 inches

Step-by-step explanation:

The volume of a cone is: , where r is the radius and h is the height.

Here, we know that V = and that h = 18, so plug these in to solve for r:

Solving for r, we get:

486 = (1/3) * 18 * r^2

r^2 = 81

r = 9

Thus, the radius is 9 inches.

Hope this helps!

9 in

Step-by-step explanation:

⅓ × pi × r² × h = Volume

⅓ × pi × r² × 18 = 486pi

r² = 81

r = 9

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
