6.) Find the surface area of the regular pyramid shown to the nearest whole number. The figure is not drawn to scale.
http://assets.openstudy.com/updates/attachments/55bff878e4b03325500374c7lollygirl2171438647128464as.jpg
my answer: 1,125 m^2. is that correct?
7.) What is the surface area of a conical grain storage tank that has a height of 37 meters and a diameter of 16 metes? Round the answer to the nearest square meter.
my answer: 1152 square meters.

Best ResponseYou've already chosen the best response.2What did you get for the base of the pyramid?, and what did you get for the area of each of the triangular faces?

Best ResponseYou've already chosen the best response.0gane just messaged me saying i was right. 6) The area of the base is 6*(15 m)*(7.5√3 m) = 675√3 m^2 ≈ 1169 m^2 .. The lateral area is 3*(15 m)*(12 m) = 540 m^2 .. The total area of base and sides is 1709 m^2. 7) The area of the base is π*(8 m)^2 = 64π m^2 ≈ 201 m^2 .. The lateral area is π(8 m)*√(37^2 + 8^2) m = 951 m^2 .. The total area of base and side surface is 1152 m^2.

Best ResponseYou've already chosen the best response.2The surface area of the pyramid is the sum of the area of its base, plus its lateral surface area The base can be decomposed into six triangles Area of base = 6 * (15m) * (7.5√3m) /2 = 1169/2 m^2 = .... m^2 Lateral area = 3*(15 m)*(12 m) = 540 m^2 The total surface area Area of base + Lateral area = .... m^2 + 540 m^2 = ( ) m^2

Best ResponseYou've already chosen the best response.0Actually it is, I have been getting corrected of my work since I got here. I havent come across this problem before until now. I don't know what you guys are talking about.

Best ResponseYou've already chosen the best response.0It isn't cheating when you are just simply asking someone if you did something correctly. Pretty much all of you guys with 99 points have been coming in and correcting me no problem. @UnkleRhaukus and @Jhannybean are the only ones who are treating it differently.

Best ResponseYou've already chosen the best response.0Because we are not solving your problem on our own and telling you whether you are right or wrong is wasting your time? Crunch the numbers yourself with the guidance we gave you and you yourself will see whether it's right or wrong. It's not difficult at all.
