The lateral area of the cylinder if the area of only the side of the cylinder and does not include the bases.
You need to find the area of the rectangle.
The width of the base is shown as 9 m.
The length of the rectangle is the same as the circumference of the bases.
The base has diameter 7 m.
Circumference = pi * d
Circumference = 3.14 * 7 m = 21.98 m
Area of rectangle = LW = 21.98 m * 9 m = 197.82 m^2
Answer: D. 198 m^2
