Question

calculate the surface area of this cylinder 582.8 cm² 291.4 cm² 560.8 cm² 329.9 cm²

Explanation:

Step1: Find the radius

The diameter \(d = 7\space cm\), so the radius \(r=\frac{d}{2}=\frac{7}{2}=3.5\space cm\)

Step2: Recall the formula for the surface area of a cylinder

The formula for the surface area of a cylinder \(S = 2\pi r(r + h)\), where \(h = 18.8\space cm\) and \(\pi\approx3.14\)

Step3: Substitute the values into the formula

Answer:

\(560.8\space cm^{2}\)
