The volume of a cylinder with height \( h \) and radius \( r \) can be found using the formula \( V=\pi r^{2} h \). Sketch a cylinder with radius 9 feet and height 10 feet, then find the volume and select the correct units. Round your answer to the the nearest tenth. Volume \( =\square \)

Find the volume of the cone above. Select the formula for the volume of a pyramid \( \frac{1}{3} \cdot h \) Areaof Base \( \cdot h \) \( l \cdot w \cdot h \) \( 2 \cdot \pi \cdot r^{2} \cdot h \) Find the volume of the square based pyramid above.
