Answer:
<h2>4200πcm²</h2>Step-by-step explanation:
Given the formula for the surface area of a cylinder as S = 2πr(r+h) where r is the radius of the cylinder's base and h is its height.
Given parameters
base radius of the cylindrical pole = 10 cm
Height of the cylindrical pole = 2 m
Since 100 cm = 1 m, then 2 m = 200 cm
Height of the cylindrical pole (in cm) = 200 cm
Required
Surface area of the pole (in cm²)
Using the formula for finding the surface area of a cylinder as shown above;
Hence the surface area of the pole in square centimetres is 4200πcm²
