To find the total area of the two bases of the cylinder, we need to calculate the area of each base and then add them together.
The formula for the area of a circle is A = πr^2, where r is the radius.
For the two bases of the cylinder:
Area = 2 * π * (2cm)^2
Area = 2 * 3.14 * 4
Area = 25.12 cm^2
Therefore, the total area of the two bases of the cylinder is 25.12 cm^2.

The correct answer is 6.28 square centimeters.
The area of one base of the cylinder is πr^2, where r is the radius. In this case, the radius is 2 cm.
Area of one base = 3.14 * (2)^2 = 3.14 * 4 = 12.56 square centimeters
Since there are two bases, the total area of the two bases is 2 * 12.56 = 25.12 square centimeters.

The formula for the lateral side area of a cylinder is the circumference of the base multiplied by the height of the cylinder.
Circumference of the base = 2πr, where r is the radius. In this case, r = 2 cm.
Height of the cylinder = 15 cm.
Circumference of the base = 2 * 3.14 * 2 = 12.56 cm
Lateral side area = Circumference of the base * Height = 12.56 * 15 = 188.4 square centimeters
Therefore, the area of the lateral side of the cylinder is 188.4 square centimeters.
That’s not an answer
Apologies for the oversight. Let's correct that.
The lateral surface area of a cylinder is calculated using the formula:
Lateral Surface Area = 2πrh
Given:
Radius (r) = 2 cm
Height (h) = 15 cm
Substitute the values into the formula:
Lateral Surface Area = 2 * 3.14 * 2 * 15
Lateral Surface Area = 188.4 square centimeters
Therefore, the area of the lateral side of the cylinder is 188.4 square centimeters.
Nope
Let's try again.
The lateral surface area of a cylinder is calculated using the formula:
Lateral Surface Area = 2πrh
Given:
Radius (r) = 2 cm
Height (h) = 15 cm
Substitute the values into the formula:
Lateral Surface Area = 2 * 3.14 * 2 * 15
Lateral Surface Area = 188.4 square centimeters
Therefore, the area of the lateral side of the cylinder is 188.4 square centimeters.
