The diameter of the cylindrical drum is approximately 6cm and a height of 4cm. What is the area of the drum?

Solution Pls

 

Answer:

The area of the cylindrical drum is approximately 132 cm².

Step-by-step explanation:

Area of cylinder = 2πrh + 2πr²

Where:

r = diameter/2  ⇒ r = (6 cm)/2   ⇒  r = 3 cm

h = 4 cm

π  = 3.14

Solution:

Area = 2(3.14)(3 cm)(4 cm)  + 2(3.14)(3 cm)²

Area = 75.36 cm² + 56.52 cm²

Area = 131.88 cm² or 132 cm²
