Solve for the first vaiable in one of the equation, then substitute the result into the other equation.
Point Form:
(3, -1)
Equation Form:
x = 3
y = -1
U mean 1 tenth?
Well, here
73.7
Start with the volume equation for a sphere:
V=4/3pi•r^3
The dimensions of the cylinder allow for a sphere with a diameter of 20 centimeters, so the radius of this sphere will be 10 centimeters. Substituting this into the equation:
V=4/3pi•(10)^3
or the uppermost right answer (B).
