Six hundred thirty two and seven hundred forty five thousandths.
600 + 30 + 2 + .7 + .04 + .005
9, i believe! please check, I’m not a super computer LOL
The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
A . Because one you make the ratio 80:48 you simplify (divide until you can divide anymore ).
