Hi! To find the surface area of a cylinder, you need to find the surface area of the base, and then the surface area of the rectangular prism that "wraps around" the cylinder.
The area of a circle: A=pi*r^2 A=3.14*3.7^2 A≈43.00
Multiply this by 2 because there are 2 circles
Combined Area of Circles = 86
Circumference of a circle = C=2pi*r (this is for the width of the rectangle) C=2(3.14)(3.7) C=23.236 C=W W=23.236 W*L=A 23.236 * 7.1=A A≈165
