Lani is making a cake in the shape of a cone. To make the cake, she uses a cone shape mold. The mold has a diameter of 10 inches and a height of 12 inches.What is the volume of the cake?Use 3.14 for pi. Round to the nearest tenth, if necessary.125.6 in³314 in³942 in³1256 in³

Accepted Solution

so, if the diameter is 10, that means the radius is half that.

[tex]\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\quad \begin{cases} r=radius\\ h=height\\ -----\\ r=5\\ h=12 \end{cases}\implies V=\cfrac{\pi \cdot 5^2\cdot 12}{3}[/tex]
