Answer:
Surface area of the cylinder is 125.6cm²✔
Step-by-step explanation:
Given that,
A right angle cylinder having a base area of 16πcm² and a height of 5cm.
Here, base area and the height is given we need to find the surface area of the cylinder.
Step 1 :
Finding the radius of the cylinder :
Base area of a cylinder is given by : πr²
From the given values :
→ Base area = πr²
→ 16π = πr²
→ 16π/π = r²
→ 16 = r²
→ √16 = r
→ r = 4cm.
Therefore we for the radius as 4cm.
Step 2 :
Finding the surface area of the cylinder :
Surface area of a cylinder is given by : 2πrh
From the given values :
→ Surface area of the cylinder :
→ 2 • 3.14 • 4 • 5
→ 125.6cm²
Therefore, surface area of the cylinder is 125.6cm² ✔
