QuestionBUSINESS A Mason jar company wants to increase the volume of its cylindrical jars by 6 cubic inches. The company's designer wants a formula that states the height $h$ of a jar given its volume $V$ and radius $r$. The volume of a cylindrical jar is modeled by the equation $V=\pi r^{2} h$. Part A What formula should be used to find the height $h$ ? A. $h=\pi \cdot r^{2}$ B. $h=\sqrt{\frac{V}{\pi r}}$ C. $h=\frac{V}{\pi r^{2}}$ D. $h=\frac{V}{r^{2}}$
Part B If the radius of the jar is 1.5 inches and the original volume is 30 cubic inches, then what height should the company make its new jar to increase the volume by 6 cubic inches?
