Q. The volume of a right cone is 1680π units 3. If its radius measures 12 units, find its height.Answer: units
Write Volume Formula: The formula for the volume of a right cone is V=31πr2h, where V is the volume, r is the radius, and h is the height of the cone. We are given the volume V=1680π units3 and the radius r=12 units. We need to solve for the height h.
Substitute Known Values: First, let's plug the known values into the volume formula: 1680π=(31)π(12)2h.
Simplify Equation: Next, we simplify the right side of the equation by squaring the radius: 1680π=(31)π(144)h.
Cancel π: Now, we can cancel π from both sides of the equation, which gives us 1680=(1/3)(144)h.
Isolate Term with h: We multiply both sides of the equation by 3 to isolate the term with h: 5040=144h.
Solve for h: Finally, we divide both sides by 144 to solve for h: h=1445040.
Final Height: After performing the division, we find that h=35 units.
