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
Answer:
13.6 and .4
Step-by-step explanation:
3.4x4=13.6
leaving .4 left
1) Point A will be at (-4,4)
2) I think an equilateral triangle can't be right triangle
