Find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximation of 3.14 for pi. (1 point, square centimeters
The formula for the surface area of a cylinder is given by:
A = (2πr^2) + (2πrh)
where A is the surface area, r is the radius, and h is the height.
Substituting the values r = 4 cm and h = 2 cm, and using the approximation of π as 3.14, we get:
A = (2(3.14)(4^2)) + (2(3.14)(4)(2))
A = (2(3.14)(16)) + (2(3.14)(4)(2))
A = (6.28(16)) + (6.28(8))
A = (100.48) + (50.24)
A = 150.72
Therefore, the surface area of the cylinder is approximately 150.72 square centimeters.
