Question 955449
For 2 half circles(top+bottom){{{A[1]}}}={{{Area=(pi)r^2}}}
... {{{A[1]}}}={{{(pi)(5^2cm^2)=25(pi)cm^2}}}
For curved side(1/2 circumference*height){{{A[2]}}}={{{Area=(pi)r*h}}}
...{{{A[2]}}}={{{(pi)(5cm)(3.5cm)=17.5(pi)cm^2}}}
...{{{A[1]+A[2]=42.5(pi)cm^2}}}
For flat side {{{A[3]}}}={{{Area=height*diameter}}}
...{{{A[3]}}}={{{(3.5cm)(10cm)=35cm^2}}}
Total surface area={{{42.5(pi)cm^2+35cm^2}}} I don't know where the inches came from.
