How To: Solve the circumference with pi

In this tutorial, we learn how to solve the circumference with pi. You will first need to know what to equation to figure out circumference is. C= (pi) x (diameter) is what the equation is. So, to figure out the circumference, first figure out what the diameter is. Once you have this, multiply it by pi. This will probably be on your calendar as a symbol, but you can also type it in as 3.14. After you multiply these two numbers together, the number you get is what the circumference is. Make su...

How To: Derive the basic area of a triangle

In this video tutorial, viewers learn how to solve the area of a triangle. The formula for the area of a triangle is A = ½ x b x h or bh/2. The base of the triangle is always at the bottom; it is the side that the triangle sits on. The height is the length between the base and the highest point of the triangle. Multiply the base and height of a triangle; then divide by two or multiply by half. The measurement unit of the answer should be squared. This video will benefit those viewers who need...

How To: Calculate the area of various polygons

We can calculate the area of the simple polygons like square, rectangle, triangle, pretty easily. Area of square can be calculated by drawing it on a graph paper, of unit cm length and breadth. Area of a rectangle is length X breadth. Area of a triangle is 1/2bh, half of product of base and height. For a parallelogram , area is the product of base and height. For a trapezoid , it is 1/2(b1+b2)h. For some other extreme polygons, we can calculate the area by making it different simple polygons ...
