For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:

Find the surface area of a sphere with a volume of 36π in3.
swat32
First use known volume to solve for radius:
V=\frac{4}{3}\pi r^{3}
r=\sqrt[3]{\frac{3V}{4\pi}}
r=\sqrt[3]{\frac{3(36\pi)}{4\pi}}
r=\sqrt[3]{27}
r=3

Then use the radius to get the surface area:
A_{surf}=4 \pi r^{2}
A_{surf}=4 \pi 3^{2}
A_{surf}=4 \pi 9
A_{surf}=36\pi\approx113.09

No solution

Step-by-step explanation:

There is no solution to the system of equations y=3x+2 and 6x-2y=8, meaning that they are parallel to each other on a graph, with no points ever intersecting on each other's lines.
