  • Radius=r=0.7m
  • Volume=231m^3
  • Height=h

\boxed{\sf Volume=\pi r^2h}

\\ \sf\longmapsto π(0.7)^2h=231

\\ \sf\longmapsto 0.49πh=231

\\ \sf\longmapsto πh=\dfrac{231}{0.49}

\\ \sf\longmapsto 3.14h=471.4

\\ \sf\longmapsto h=\dfrac{471.4}{3.14}

\\ \sf\longmapsto h=150m

Is this a function??
Blizzard [7]
Yes this is a function because the definition of a function is if the x doesn’t repeat and we can test this with the vertical line test that states that if you put an imaginary line where the points are the x shouldn’t repeat in this case this is true as the x doesn’t repeat
