Question

Find the curved surface area of a cylinder if it's base circumference is 36 cm and it's height is 4 cm​

Answer 1

Answer:

CSA of a cylinder = 144cm²

Step-by-step explanation:

Given the following data;

Base circumference = 36cm

Height = 4cm

To find the curved surface area (CSA) of the cylinder;

CSA of a cylinder = 2πr * h

But 2πr = 36cm

Substituting the values into the equation, we have;

CSA of a cylinder = 36 * 4

CSA of a cylinder = 144cm²
