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.

Answer:
5.269
Step-by-step explanation:
We shall match the decimal points, after integer value 5. Since
269 is greater than 038. So , 5.269 is greater than 5.038
Answer:
(5/4-3/4)
divide both sides by -7 then line them up and solve the equation and delete one variable.
70℅ = 14
100 = X
70X = 1400
X = 1400/70
X = 20
