So we want to know the volume of a sphere in terms of pi if we know the area of the sphere is equal to A=9pi. So the area of the sphere is A=4*pi*r^2 and the volume V=(4/3)*pi*r^3. We can get the radius from the area: 9pi=4*pi*r^2 and we see the pi cancels out: 9=4*r^2. We divide by 4 and take the square root: r=sqrt(9/4)=3/2. So r=3/2 and we can input it into volume V.
V=(4/3)*(3/2)^3*pi=(4/3)*(27/8)*pi=(9/4)*pi.
So the volume of the sphere is V=(9/4)*pi cubic feet.
Standard form of a line is
Ax+By=C
slope-intercept form of a line is
y=mx+b
where m is the slope and b is the intercept
if you convert standard form intoslope intercept
Ax+By=C
By=-Ax+C
y= -A/B *x +C/B
slope -- m= -A/B
y-intercept --b= C/B
It's like fractions, to simplify you divide all by 2 and get 4:2:3
8 days. You take the number of cups and divide it by how many cups and you get how many times she is able to pour the milk (aka the number of days) (6/ .75=8)
