Find the surface area of a cylinder with a radius of 4cm and a height of 2cm. Use the approximation of 3.14 for pi. (1 point)
The formula for the surface area of a cylinder is given by:
Surface Area = 2πr(r + h)
Given that the radius (r) is 4cm and the height (h) is 2cm, we can substitute these values into the formula:
Surface Area = 2 * 3.14 * 4(4 + 2)
Simplifying the expression inside the parentheses:
Surface Area = 2 * 3.14 * 4(6)
Multiplying 4 by 6:
Surface Area = 2 * 3.14 * 24
Calculating the product of 2, 3.14, and 24:
Surface Area = 150.72 cm²
Therefore, the surface area of the cylinder is approximately 150.72 cm².
