Volume
502.6548cu units
Total Surface Area
351.8584sq units
Lateral Area
251.3274sq units
Step by step
Volume
V = π × 4² × 10
= 502.6548
Lateral area
LA = 2π × 4 × 10
= 251.3274
Total surface area
SA = LA + 2π4²
= 351.8584
How it works
A right circular cylinder's volume is the base area times height (πr²h). The lateral surface unrolls into a rectangle of width 2πr and height h.

Frequently Asked Questions
What is lateral area?
The area of the curved surface only, excluding the two circular bases: 2πrh.
How do I find the radius from volume and height?
r = √(V/(πh)). Divide volume by πh, then take the square root.
