The 4 in 46,395 is 10 times the 4 in 14,906.
Answer:
9 3/4 inches
Step-by-step explanation:
If we are finding how much taller Sara is, we need to subtract
6 ft 3 3/4 - 5 ft 6in
I like to line up vertically
6 ft 3 3/4
- 5 ft 6in
----------------
We need to borrow 1 ft and make it 12 inches
5 ft 3+12 3/4
- 5 ft 6in
----------------
5 ft 15 3/4
- 5 ft 6in
----------------
0 9 3/4 inches
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
3rd option would be correct in my opinion
