Hello,

f(x)=6(x+2)-3=6x+12-3=6x-9

y=6x-9==>x=6y-9==>6y=x+9==>y=(x+9)/6
if x=21 then y=(21+9)/6=30/6=5

f^(-1)(21)=5

The radius of a basketball is 4.7 inches.what the volume of the basketball? Round to the nearest 10
asambeis [7]
The formula for the volume of a sphere is V= \frac{4}{3}  \pi r^3. Plugging in 4.7 for your radius, we get V= \frac{4}{3} \pi 4.7^2= \frac{4}{3} \pi 22.09= \frac{88.36}{3} \pi, which is roughly 29.453π≈92.530.
