Area of the circular base of the cylinder = πr^2
Area = 3.14 * 7^2
Area = 3.14 * 49
Area ≈ 153.86 in^2
Width of the lateral face of the cylinder = circumference of the base = 2πr
Width = 2 * 3.14 * 7
Width ≈ 43.96 in
Area of the lateral face of the cylinder = height * width
Area = 14 * 43.96
Area = 615.44 in^2
Total surface area of the cylinder = 2 * (area of circular base) + (area of lateral face)
Total surface area = 2(153.86) + 615.44
Total surface area = 307.72 + 615.44
Total surface area = 923.16 in^2
the surface area of the Cylinder it has 7in the radius on top and on the right side, the hight is 14in
Remember to use 3.14 for π. Round to the nearest hundredths place (2 digits after the decimal).
