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.
Answer: y=4/3x+2
Step-by-step explanation:
-4x-3y=6
+4x +4x
-3y=4x+6
-3/-3=4/3+6/3
y=4/3x+2
3 2/6 is your answer...............
2x-y= -5
x-y=0 ....> x = y
Substitute x = y into 2x-y= -5
2x - x= -5
x = -5
x = y = -5
Answer
(-5 , -5)
Answer:
I would say its 100 times greater
Step-by-step explanation: Because you have to move 3 times which is passed the ones and the tens so then its ends up to the hundreds place
