Cylinder Volume Formula

$V = \pi r^2 h$V=πr2h

$r$r

$h$h

$A_{\text{base}} = \pi r^2 \approx 28.27$Abase​=πr2≈28.27

$V = \pi r^2 h \approx 226.19$V=πr2h≈226.19r = 3.0h = 8.0

---

Total Surface Area Formula

$A = 2\pi r(h + r)$A=2πr(h+r)

---

Lateral Surface Area Formula

$A_L = 2\pi r h$AL​=2πrh

Practical Example

Let’s assume:

• Radius = 3 cm
• Height = 10 cm

Step 1: Volume

V = π × 3² × 10
V ≈ 282.74 cm³

Step 2: Surface Area

A = 2π × 3 × (10 + 3)
A ≈ 245.04 cm²
