Given side length a calculate the perimeter Given angle B calculate angles A, C and D Given angle A calculate angles B, C and D The following formulas, based on those above, are used within this calculator for the selected calculation choices. K = ah = a 2 sin(A) = a 2 sin(B) = pq/2 Height: h Rhombus Formulas & Constraints Corner Angles: A, B, C, D The units are in place to give an indication of the order of the calculated results such as ft, ft 2 or ft 3. Units: Note that units of length are shown for convenience. square millimeters, square centimeters, square meters, and square kilometers. Parallelogram with all 4 sides equal length. Use the radius of a circle to find the diameter, circumference, and area. A rhombus whose angles are all right angles is called a Calculations include side lengths, corner angles, diagonals, height, perimeter and area of a rhombus.Ī rhombus is a quadrilateral with opposite sides parallel and all sides equal length. The number π has application in calculating statistical distributions like the normal distribution (gaussian distribution), which are used throughout the sciences.These 2 drawings refer to the same single rhombus.Ĭalculate certain variables of a rhombus depending on the inputs provided. To find the perimeter of the square pool just multiply 10 by 4 to get 40 meters.
For a real-world example, take a square pool that you need to encompass in rope completely. Then the perimeter is simply 2 x 4 8 inches. The invention of the wheel was one of the transforming events in early human history, as it dramatically reduced the energy expended in moving stuff around and made travelling easier. To apply the formula, assume the side of a square is given to be 2 inches. cylinders, tubes, gears, and others are used by engineers in clocks, bikes, cars, trains, ships, planes, and even rockets. The famous Ferris-wheel attraction is a circle, as are the wheels on your car or bike. Circles are used when planning athletic tracks, recreational areas, buildings, and roundabouts, so knowing their area is important in construction, landscaping, etc. Practical applicationĬircle geometry has a wide array of practical uses. Apply the second equation to get π x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters). Task 2: Find the area of a circle given its diameter is 12 cm. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Use this calculator to easily calculate the area of a circle, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc.
Task 1: Given the radius of a circle, find its area.
