Answer 2

Answer:

For Figure 1

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{14}}\put(9,17.5){\sf{8}}\end{picture}$

We know the T.S.A of cylinder

Total Surface Area of Cylinder = 2πr( r + h )

• Radius = 14 cm
• Height = 8 cm

Substituting the values in the formula :-

↬ 2 × 22/7 × 14 ( 14 + 8 )

↬ 2 × 22 × 2 ( 22)

↬ 44 × 44

↬ 1936 cm²

For figure 2 :-

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{2}}\put(9,17.5){\sf{2}}\end{picture}$

Total Surface Area of Cylinder = 2πr( r + h )

• Radius = 2m
• Height = 2m

Substituting the values in the formula :-

↬ 2 × 22/7 × 2 ( 2 + 2)

↬ 2 × 22/7 × 2 ( 4)

↬ 44/7 × 8

↬ 50.24 m²
