Math 3 Volume Formulas

A = \frac{1}{2}bh, where A is the area, b is the base, and h is the height.

C = 2\pi r, where C is the circumference and r is the radius.

A = lw, where A is the area, l is the length, and w is the width.

V = \frac{4}{3}\pi r^3, then divide by 2 to get the volume of the hemisphere.

A = \pi r^2, where A is the area and r is the radius.

The diameter is twice the radius, d = 2r.

V = \pi r^2 h, where V is the volume, r is the radius, and h is the height.

V = \frac{1}{3}\pi r^2 h, where V is the volume, r is the radius, and h is the height.

SA = 4\pi r^2, where SA is the surface area and r is the radius.

V = \frac{4}{3}\pi r^3, where V is the volume and r is the radius.
