The semi circle and isosceles triangle have the same base AB and the same area. Find angle x. Show workout.

Nina [5.8K]

$r= \frac{AB}{2} \\ \\A_{semi\:circle }=\frac{r^2\pi}{2} \\ \\A_{triangle}=A_{semi\:circle }=\frac{r^2\pi}{2} \\ \\A_{triangle}= \frac{2r\times h}{2} =rh \\ \\\frac{r^2\pi}{2}= rh \\ \\h=\frac{r\pi}{2} \\ \\ \tan{x}= \frac{h}{r} = \frac{\frac{r\pi}{2}}{r} =\frac{\pi}{2} \\ \\x=\arctan{\frac{\pi}{2}}
\\
\\x \approx 57.52^o$

Find the volume of the cone. Round your answer to the nearest tenth.

oee [108]

Answer:

15205.3

Step-by-step explanation: H=30 R²=484 3.14=π →= rounded up to tenth V = Volume

<em><u>formula (no numbers): H x R² x π ÷</u></em><u> </u> $\frac{1}{3}$ <u> (or 3) </u><em><u>= V</u></em>

<u><em>how i got the answer : 30 x 484 x 3.14 ÷ 3 = 15205.31 → 15205.3</em></u>

Please help, will give brainliest to first

Lelechka [254]

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that $\frac{AN}{FN} =\frac{OR}{FR}$

Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have $AN = \frac{(FN)(OR)}{FR}$

Substituting in the known values we have $AN=\frac{(10)(11.2)}{7} =16$
