Details of cost for 10 metre length pipe
Area = WxD1 + 2x½xR Cot QxR - [R²/2(3.14/2-Q)] - (3.14/2)R²
= WD1 + R²(Cot Q) - R²(3.14/2 - Q) - (3.14/2)R2
= WD1 + R²(Cot Q - 3.14 + Q)
Where Sin Q = [R/(W/2)] = 2R/W
W = D + X ; X = 300 mm, D = 200+ 17 + 17 = 234 mm
W = 234 + 300 = 534 mm
D1 = Depth = 150 + (½ x 234) = 267 mm
R = 117 mm
Sin Q = (2x117)/534 = 0.4382 therefor Q= 26°0'
Hence Tan Q = 0.4877
Area = 534 x 267 + (117)² (Cot Q - 3.14 + Q)
= [142578 + 13689 (1/0.4877 - 180°+ 26°0')] sqmm
= [142578 + 13689 (2.05 - 154°0' x 3.14/180)] sqmm
= [142578 + 13689 x (2.05-2.69)] sqmm
= [142578 + 13689 x (-0.64)] sqmm
= (142578 - 8760.96) sqmm
= 133817.04 sqmm
