The number π has application in calculating statistical distributions like the normal distribution (gaussian distribution), which are used throughout the sciences. Volume V and area A calculations are essentially for half of a sphere. A hemisphere is 1/2 of a sphere cut in half by passing a plane through the center of the sphere. Just type the number to convert into the box and hit the calculate button. It also calculates the variables in terms of PI. Use our handy calculator to convert between cubic centimeters and other units of volume. Round up if this number is greater than or equal to 5 5. 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. This online calculator will calculate the various properties of a hemisphere given any 1 known variable. Find the number in the tenth place 6 6 and look one place to the right for the rounding digit 8 8. The prefix centi is derived from the Latin centum meaning hundred and is symbolized as c in the Metric System. The base unit for a centimeter is meter and the prefix is centi. The symbol for centimeter is cm and the International spelling for this unit is centimetre. cylinders, tubes, gears, and others are used by engineers in clocks, bikes, cars, trains, ships, planes, and even rockets. A centimeter is a unit of Length or Distance in the Metric System. To calculate the total surface area you will need to also calculate the. Total surface area of a closed cylinder is: A L + T + B 2 rh + 2 ( r 2) 2 r (h+r) The area calculated is only the lateral surface of the outer cylinder wall. The famous Ferris-wheel attraction is a circle, as are the wheels on your car or bike. Calculate the top and bottom surface area of a cylinder (2 circles ): T B r 2. 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. Task 1: Given the radius of a circle, find its area.
