Areas: The area of a triangle = half × base × height The area of a circle = pr² (r is the radius of the circle) The area of a parallelogram = base × height Area of a trapezium = half × (sum of the parallel sides) × the distance between them [ 1/2(a+b)d ]. Area of a Trapezium mathsteacher.com.au. A trapezium is a quadrilateral that has only one pair of parallel sides. Consider the area of the following trapezium. To calculate the area of a trapezium, divide it into a rectangle and two triangles as shown below.

A list of all the formulae needed for your GCSE maths exam. Click a formula for an interactive example to show how it is used.

The trapezium rule works by splitting the area under a curve into a number of trapeziums, which we know the area of. If we want to find the area under a curve between the points x 0 and x n , we divide this interval up into smaller intervals, each of which has length h (see diagram above). Radius of the circle circumscribed about an isosceles trapezium; Radius of the circle circumscribed about a regular hexagon; Radius of the circle circumscribed about a regular polygon; Surface area of geometric shapes. Площадь поверхности куба; Surface area of a parallelepiped; Surface area of a regular pyramid

Formula: A = 0.7854 x a x b, where a = length of the ellipse, and b = shorter dimension (width) Example:a = 15 ft. b = 5 ft. A = 0.7854 x 15 x 15 = 58.9 sq. ft. IRREGULARLY-SHAPED AREA Method I. Determination of a very irregularly shaped area can be obtained by establishing the longest line possible lengthwise throug the center of the area.

Looking at the cube template, it is easy to see that the cube has six sides and each side is a square. The area of one square is a × a = a 2 . Since there are six sides, the total surface area, call it SA is: SA = a 2 + a 2 + a 2 + a 2 + a 2 + a 2 . SA = 6 × a 2 . Example #1: Find the surface area if the length of one side is 3 cm.

Section 2: Surface Area. Recap: Grade B and C. You should be familiar with finding the surface area of prisms (such as cuboids, triangular prisms, etc). The surface area of a prism is found by adding together the area of each face. Examination style question. Find the total surface area of the solid prism shown in the diagram.
