area of circles= pi×radius^2
7÷2=3.5 (radius)
2×( pi×3.5^2)=76.969 inches^2 (I multiplied it by 2 because there are 2 circles)
The circumference in this example is actually the width of the rectangle created by the cylinder. To work it out you do:
pi× diametre diametre =7
pi×7= 21.99 inches^2
to get surface area you add both up...
76.969+21.99= 98.959 inches^2
you can round that to 98.96 inches^2
