Answer:
6.5
Step-by-step explanation:
X + Y= 8
If you plug the value (3, 5) for x and y, you will arrive at your destination (answer).
X=3
Y=5
3 + 5 = 8
So first you would go 1+y=1 and the go 1+0=1
First you need to find the radius. To do that you need to divide the diameter by two;
45 / 2 = 22.5
Then you plug the radius in the formula for a sphere. Which is...
V = (4 / 3)πr^3
First you need to find the volume with out pi
V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
