Solve the Problem S=2π(R1+R2)(h+R1R2),S = 2 \pi \left( R _ { 1 } + R _ { 2 } \right) \left( h + R _ { 1 } - R _ { 2 } \right) ,

Question 14

Multiple Choice

Solve the problem.
-The surface area of a hollow cylinder (tube) is given by S=2π(R1+R2) (h+R1R2) ,S = 2 \pi \left( R _ { 1 } + R _ { 2 } \right) \left( h + R _ { 1 } - R _ { 2 } \right) , where h\mathrm { h } is the length of the cylinder and R1\mathrm { R } _ { 1 } and R2\mathrm { R } _ { 2 } are the outer and inner radii. If h,R1\mathrm { h } _ { , } \mathrm { R } _ { 1 } , and R2\mathrm { R } _ { 2 } are measured to be 10 inches, 3 inches, and 5 inches respectively, and if these measurements are accurate to within 0.10.1 inches, estimate the maximum possible error in computing SS .
