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
A:
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]
