The volume of a sphere:
$V=\frac{4}{3} \pi r^3$
r - the radius

The diameter is twice the radius.
$d=36 \ in \\
r=\frac{36}{2} \ in = 18 \ in \\ \\
V=\frac{4}{3} \pi \times 18^3=\frac{4}{3}\pi \times 5832=\frac{23328}{3} \pi=7776\pi \ [in^3]$

The exact volume of the sphere is 7776π in³.

Mathematics

k = 45

Step-by-step explanation:

k (constant of proportionality) = y / x

y = 135 and 225 and x = 3 and 5

So you do 135 / 3 which is 45

And then 225 / 5 is also 45

Therefore the constant of proportionality (k) is 45
