Answer: 520.5 m²
This answer is not an answer choice provided, but I hope this still helps.
Step-by-step explanation:
The formula to find the surface area of a cone is
. Looking at the formula, we can see there are radius and height. The figure provided gives the radius is 7.1 m and height of 14.6 m. Since we have these values, we can just plug them into the formula.
![A=\pi (7.1)(7.1+\sqrt{14.6^2+7.1^2} )](https://tex.z-dn.net/?f=A%3D%5Cpi%20%287.1%29%287.1%2B%5Csqrt%7B14.6%5E2%2B7.1%5E2%7D%20%29)
Now that we have filled out the formula, we can plug this into a calculator to get the surface area. It is possible to do this by hand, but it is hard to be accurate.
![A=520.5m^2](https://tex.z-dn.net/?f=A%3D520.5m%5E2)
The answer is 4.2 x 10^-6
5 19 6 -18
-3
-15 -12 18
5 4 -6 0
Therefore, the width is 5x^2 + 4x - 6
Answer:
segment FG = one half segment FI, segment FH = one half segment FE, and segment HG = one half segment EI; ΔHFG ~ ΔEFI
