Cylinder
Height: 14in
Radius: 7in
Determine the area of the circular base of the cylinder:
square inches
Determine the width of the lateral face of the cylinder:
inches
Determine the area of the lateral face of the cylinder:
square inches
What is the total surface area of the cylinder:
square inches
Area of the circular base of the cylinder: π(7in)^2 = 49π square inches
Width of the lateral face of the cylinder: This is the same as the circumference of the base circle, which is 2π(7in) = 14π inches
Area of the lateral face of the cylinder: Height * width = 14in * 14πin = 196π square inches
Total surface area of the cylinder: Base area + lateral face area + lateral face area = 49π + 196π + 196π = 441π square inches ≈ 1385.44 square inches
