Calculate the volume of a cone where the dimensions are all given in the same units STEP \( 2 \)

Jessica is trying to work out the volume of this cone. ![A cone with the slant height labelled 9cm, the perpendicular height labelled h and half the cone's base (forming a right angled triangle with the slant and perpendicular heights) is labelled 6cm.]() First she needs the perpendicular height.

Which of the following equations is true? \( h^{2}=9^{2}+6^{2} \)
