a farm supply store sells a variety of treat balls for small and large animals. martha wants to purchase a ball that can hold 1437 cubic centimeters of treats. what is the diameter of the ball she should purchase? round to the nearest whole number.
the volume of a sphere is v=4/3 x 3.14 r to the the third power

14 centimeters.

Step-by-step explanation:

You need to use the formula for calculate the volume of a sphere:

Where the radius of the sphere is "r".

As you know the volume of the ball, you can susbtitute it into the formula , and solve for the radius "r":

The diameter of the ball can be calculated with:

Where r is the radius of the ball.

Substituting the radius of the ball into  , you get that the diameter of the ball that she should purchase, rounded to the nearest whole number, is:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
