When estimating the number of spheres contained in a prism we should account for the empty space between the spheres. to do this we find 190% of the volume of the sphere and use that value in our estimation.
if gumballs have a 2 inch diameter, what should we use as the volume of each gumball in our calculation? (round your answer to the nearest tenth)
a. 4.2 cubic inches
b. 8.0 cubic inches
c. 33.5 cubic inches
d. 5280 cubic inches

B. 8.0 cubic inches

Step-by-step explanation:

You need to find 190% of the volume of a gumball which is a sphere.

To find 190% of a quantity, multiply the quantity by 1.9.

volume of sphere = (4/3)(pi)(r^3)

diameter = d = 2 in.

radius = r = (1/2)d = (1/2)(2 in.) = 1 in.

volume of sphere = (4/3)(3.14159)(1 in.)^3 = 4.189 in.^3

The volume of a gumball is 4.189 in.^3

Now we need 190% of that volume.

190% of volume of sphere = 1.9 * volume = 1.9 * 4.189 in.^3 = 7.959 in.^3

Rounded to the nearest tenth, the volume is

B. 8.0 cubic inches

5.5

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
