Area = 1/2*(sum of the two bases)*height What is the formula for a trapezoid? The perimeter of a trapezoid is the sum of the lengths of each side. To find the area of a trapezoid: add base 1 and base 2 together then divide that answer by 2, then multiply it by the height of...
A prism is a polyhedron that has bases that can have an {eq}n {/eq} number of sides and connected to each other by parallel lines forming planes. In a right prism these bases and planes would be perpendicular to each other forming right angles with each other....
The formula for calculating the area of a circle is: Area = π * r²Where "Area" is the circle's area.(pi) is a Mathematical constant with an approximate value of 3.14159. r is the radius of the circle, which is the distance squared (raised to the power of 2) from the circle'...
