The answer is false.

The formula for the SA of a cone is \pi r^{2}+\pi rl where <em>r</em> is the radius of the base and <em>l</em> is the slant height.
Since we have both the slant's height and the radius of the base we can answer this just by plugging numbers in;
SA=\pi r^{2}+\pi rl\\&#10;SA=\pi (2^{2})+\pi (2)(6)\\&#10;SA=4\pi+12\pi\\&#10;SA=16\pi\\
16\pi≈50.2654...

So your answer is false.

If it was 25%, it would be a 90 degree angle. So we can calculate this using a proportion. 25/90 = 24/x. Cross multiply to get 25x = 2160. When you divide by 25 on both sides you get 86.4. So the angle should be 86 degrees. Hope this helps.

Write a proportion you could use to convert 2.5 gallons to quarts.
marusya05 [52]
We know there are 4 quarts in a gallon, so how many quarts in 2.5 gallons anyway?

\bf \begin{array}{ccll}&#10;quarts&gallons\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;4&1\\&#10;x&2.5&#10;\end{array}\implies \cfrac{4}{x}=\cfrac{1}{2.5}\implies \cfrac{4\cdot 2.5}{1}=x
