Answer:
Cir of front wheel = pi x d = 3.14 x 12 = 37.7 in.
Cir of rear wheel = pi x d =3.14 x 18 = 56.52
Revolutions of front Tire = 300 / 37.7 = 7. 96 revolutions
Revolutions of rear Tire = 300 / 56.5 = 5.31 revolutions
Revolutions Front - Revolutions Rear = 7.96 -56.31 = 2.7 revolutions more

Answer:
V = 2000r³/3
Step-by-step explanation:
We know that the base is a circular disk, so it creates a circle on the xy plane. It would be in the form x² + y² = r². In other words x² + y² = (5r)². Let's isolate y in this equation now:
x² + y² = (5r)²,
x² + y² = 25r²,
y² = 25r² - x²,
y = √25r² - x² ---- (1)
Now remember that parallel cross sections perpendicular to the base are squares. Therefore Area = length^2. The length will then be = 2√25r² - x² --- (2). Now we can evaluate the integral from -5r to 5r, of [ 2√25r² - x² ]² dx.
As you can see, your exact solution would be, V = 2000r³/3. Hope that helps!
Hint:
"a" is the major component, "b" is the minor, the vertical axis is b+b
