of the cylinder, we get a rectangle. The measure of the area of the rectangle is the lateral area of the

cylinder. The lateral area of the cylinder can be found by using the formula

L.A. = pi * r

where r is the radius of the cylinder,

h is the height of the cylinder

L.A. = pi * r

L.A. = 11088 / 7 = 1584

Thus the lateral area of the given cylinder is 1584 square centimeters.

barrel is 7 feet and radius is 2 feet. What is the cost of painting if cost per square foot is $1.5.

L.A. = pi * r

Cost of painting one square foot of the area = $ 1.5

Cost of painting the lateral surface of the cylinder = 88 * 1.5 = $132.
