We know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere
if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere
if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere
examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area
2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area
3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area

He walked 3/8 of a mile this weekend. You multiply the numerator in 3/4 by the numerator in one half, and get a numerator of 3. You multiply the denominator of 3/4 by the denominator of 1/2, and get a denominator of 8
There are 10 people and you want each of them to have 3 cupcakes. So multiply 10x3, which is 30. Then divide 30 by 8. You can't do that without a remainder though. So you round up to the nearest multiple of 8, which is 32. Then divide 32 by 8, which is 4. So tell dad to bake 4 batches, and the rest is for your dessert tomorrow.
