Erica has a sphere shaped bouncy ball with
a diameter of 2 inches. michelle has a
sphere shaped bouncy ball with a diameter
of 4 inches. to the nearest tenth, how much
more space is occupied by michelle's
bouncy ball than erica's?

a) 29.3 in³
b) 33.5 in³
c) 4.2 in³
d) 12.4 in³

Erica: 4.2 in 3

Michelle: 33.5 in 3

Then we subtract:

33.5 - 4.2 = (29.3 in 3)

Best of Luck to you!

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
