A b 2 a 2 2ab b 2. H height of the triangle. Where r sphere radius and. A b a b a 2 b 2.

When we know the radius r of the circle and arc length l. Where a length of the sides of a square. Surface area and volume of a sphere. A b 2 a 2 2ab b 2.

X a x b x 2 a b x ab. Some of the examples of 2d shapes are square rectangle circle triangle and so on. Area of the sector l r 2. Here we provide you with common geometry formulas for some basic shapes.

A three dimensional circle is known as a sphere. Volume 1 6 π h 3a 2 3b 2 h 2 top surface area π b 2. X a x b x 2 b a x ab. The following represents some of the most common shapes in geometry and their formulas for perimeter area volume surface areas and circumference.

Perimeter l l w w 2 l 2 w. We know w 5 and h 3 so. Area of a triangle a b h. When we know the radius r of the circle and central angle θ of the sector.

Two dimensional shapes are the shapes that can be drawn on the piece of paper. X a x b x 2 a b x ab. Where b base of the triangle. Surface area and volume of a cylinder.

In order to calculate either the surface area or the. Area of a square a a 2. P 2 l w a lw. Surface area and volume of a cone.
