Answer:
<h2>A cone: B. V = 100.48 cubic units</h2><h2>A cylinder: C. V = 301.44 cubic units</h2>Step-by-step explanation:
The formula of a volume of a cone:
<em>r</em> - radius
<em>H</em> - height
We have <em>r = 4 u</em> and <em>H = 6 u</em>. Substitute:
If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.
Therefore, the volume of acylinder:
Why?
The formula of a volume of a cone:
The formula of a volume of a cylinder:
Therefore
If the radius and height are the same.
