4^45
When you have exponents like that, you have to multiply them together. So, 9*5 =45
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
Keep in mind: L*W = A, and thus W = A/L.
756 sq in
Here, W = -------------- = 7 inches.
108 in
Answer:
x=8
Step-by-step explanation:
Make all the denominators the same
3(x-4/10)=6(3/5)-2(x-5/15)
(3x-12)/30=18/30-(2x-10)/30
Cancel out all the denominators because they're the same
3x-12=18-2x+10
3x-12=28-2x
Add 12 to both sides
3x=40-2x
Add 2x to both sides
5x=40
Divide both sides by 5
x=8
