Best ResponseYou've already chosen the best response.0the first one is composed of 2 triangles: 4x5 + 4x5 = 40m 3 rectangles: 4x14 + 5x14 + \[14\times \sqrt{4^{2} + 5^{2}}\] and you add all of them up

Best ResponseYou've already chosen the best response.0Area of triangle is BH/2, in this figure that equals (4 x 5)/2=20/2=10 sq M, but their are two so the surface area of the triangular portion would be 20 sq meter.

Best ResponseYou've already chosen the best response.0The suface of the sides are as indicated by tacolover. 5x14= 70 sq M for one side. 4x14=56 sqM for another side and 14 x sq rt(16+25) \[\sqrt{41}\times14\]

Best ResponseYou've already chosen the best response.0yes as long as you remember that the B is a triangle and their are two of them.

Best ResponseYou've already chosen the best response.0It is a cylinder or like a can. Too find the total surface area you calculate the area of the ends which are circles (don't forget their are two of them. Then the body is actually a rectangle which has one side equal to the circumference of the circle times the height.

Best ResponseYou've already chosen the best response.0so id use 2*pi*r^2+2*pi*r*h

Best ResponseYou've already chosen the best response.0Do you know how calculate the area of circle whose diameter is 8cm or radius would be 1/2 of that or 4 cm.??

Best ResponseYou've already chosen the best response.0The area of the ends would be as you have but it would be like 2(2*pi*r^2). Then the can (not the ends) would be h*C 8*piD=8*pi*8

radar

Best ResponseYou've already chosen the best response.0I am sorry I got the area wrong for the ends. The formula is pi*r^2 so the ends would be 2(pi*r^2) that is for both ends

anonymous

Best ResponseYou've already chosen the best response.0so for r would it be half the diameter (8).. so 2(3.14*4^2)

radar

Best ResponseYou've already chosen the best response.0Yes that gives you the area for the ends of the cylinder. both

Best ResponseYou've already chosen the best response.0Let me check yes for the ends. Now this must be added to the surface area of the body of the can pi*D*h

Best ResponseYou've already chosen the best response.0Right now add the end area to your 301.44

Best ResponseYou've already chosen the best response.0than i would add 100.48+301.44=401.92

Best ResponseYou've already chosen the best response.0Yes that would give you the total surface area of the can, I forgot that the heigth was 12 and put 8 but you caught it!

Best ResponseYou've already chosen the best response.0I used calculator and got 326.73, so I would say you used the correct procedure and don't forget what the units are.......sq M
