Geometry Area & Volume Calculator

Calculate area, perimeter, circumference, and volume for various geometric shapes with step-by-step mathematical breakdowns.

Area mode starts with circle formulas but includes rectangle and triangle tabs for common geometry homework and design checks.

Calculated Dimensions

Area153.9380
Circumference43.9823
Diameter14

Solving Formulas & Steps:

Diameter (d) = 2 × r = 2 × 7 = 14
Circumference (C) = 2 × π × r = 2 × π × 7 ≈ 43.9823
Area (A) = π × r² = π × 7² ≈ 153.9380

Frequently Asked Questions

What is the formula for the volume of a cylinder?

The volume of a cylinder is computed as V = π × r² × h, where r is the radius of the circular base and h is the height of the cylinder.

How does the circumference of a circle relate to its area?

Both depend on the radius. Circumference is C = 2πr, while Area is A = πr². If you double the radius, the circumference doubles, but the area quadruples (2² = 4).
