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

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
