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
