Geometry Calculator
Calculate area, perimeter, volume, and other properties of geometric shapes
◼️
Square Formulas
Area = a²
Perimeter = 4a
Diagonal = a√2
▭
Rectangle Formulas
Area = l × w
Perimeter = 2(l + w)
Diagonal = √(l² + w²)
▲
Triangle Formulas
Area = ½ × b × h
Perimeter = a + b + c
●
Circle Formulas
Area = πr²
Circumference = 2πr
Diameter = 2r
🔴
Sphere Formulas
Volume = (4/3)πr³
Surface Area = 4πr²
⛽
Cylinder Formulas
Volume = πr²h
Surface Area = 2πr(h + r)
🔺
Cone Formulas
Volume = (1/3)πr²h
Slant Height = √(r² + h²)
Surface Area = πr(r + √(r² + h²))
⬛
