For the 3D solid shape represented by the orthographic views

For the 3-D solid shape represented by the orthographic views given below, determine the: a) Total surface area b) Total volume c) Scale for this drawing using the 1:10 side of the engineering scale 4.00 in

Solution

a) surface area of cone = r(r*r+h*h)^0.5=x2(4+4*4)^0.5= 28.1

Surface area of cylinder = dh = x4x6=75.4

Total surface area = 103.5 in2.

B, Volume of cone = rrh/3 = x2x2x4/3=16.76

Volume of cylinder = rrh = x2x2x6 = 75.4

Total volume = 92.16 in3.

C, 1 in = 10 in
