The approximate difference in their volumes is 17.2 cubic inches
<h3>How to determine the difference in the volume?</h3>
The given parameters are:
Diameter, d = 2.8
Diameter, D = 3.8
The radii are the half of the diameter.
So, we have:
r = 1.4
R = 1.9
The volume of the balls is then calculated using:

The difference is then represented as:

Substitute known values

Evaluate
D = 17.2
Hence, the approximate difference in their volumes is 17.2 cubic inches

Answer:
V= 18.75 cm^3
Step-by-step explanation:
- The formula for finding the volume for <em>any</em> given shape is V = L x W x H.
- So, multiply 2 1/2 cm x 2 1/2 cm x 3 cm.
- This gives you 18.75 cm^3
Answer:
(-3,-8)
Step-by-step explanation:
okay so what we can do here is elimination
we can do this first by multiplying the entire second equation by 2
so then it would become
2(5x-2y=1)
10x-4y=2
now we can add the two equations together which will eliminate y
so
-8x+4y=-8 plus
10x-4y=2 equals
2x=-6
we did that by combining like terms
next we can simplify that
x=-3
now we can plug that into the equation
-8(-3)+4y=-8
simplify
24+4y=-8
4y=-32
y=-8
our answer would be
(-3,-8)
Answer:
the answer is 15
Step-by-step explanation:

One century is 100 years, therefore 800 years is 8 centuries.
