Surface Area Calculator
Calculate the surface area of various 3D geometric shapes
Formula:
Surface Area = 4 × π × Radius²
A = 4πr²
Formula:
Surface Area = π × r × (r + √(h² + r²))
A = πr(r + √(h² + r²))
Formula:
Surface Area = 6 × Side²
A = 6a²
Formula:
Surface Area = 2 × π × r × (r + h)
A = 2Ï€r(r + h)
Formula:
Surface Area = 2 × (lw + lh + wh)
A = 2(lw + lh + wh)
Formula:
Surface Area = 2 × π × r × (2r + h)
A = 2Ï€r(2r + h)
Formula:
Surface Area = 2 × π × R × h
A = 2Ï€Rh
Formula:
Surface Area = π × (r + R) × √((R - r)² + h²) + π × (r² + R²)
A = π(r + R)√((R - r)² + h²) + π(r² + R²)
Formula (Approximation):
Surface Area ≈ 4π × [((aᵇ × bᵇ + aᵇ × cᵇ + bᵇ × cᵇ)/3]^(1/b) where b ≈ 1.6075
Formula:
Surface Area = a² + 2a√((a/2)² + h²)
A = a² + 2a√((a/2)² + h²)
How to use this calculator:
