From the diameter and the circumference, we can find the radius and then find the area of a circle. The area of a circle can be calculated in intermediate steps from the diameter, and the circumference of a circle. The area outside the boundary of the park The bigger area of the park, other than the Play area ![]() The smaller area of the park, which is shown as the Play area ![]() Straight Line Distance between Entrance Gate and Exit Gate through the fountain We can identify the various parts of a circle with the help of the figure and table given below.ĭistance from the fountain to the Entrance gate Let us understand the different parts of a circle using the following real-life example.Ĭonsider a circular-shaped park as shown in the figure below. For a circle with radius ‘r’ and circumference ‘C’: Where 'r' is the radius of the circle and π is the mathematical constant whose value is approximated to 3.14 or 22/7. The circumference can be measured by using the given formula: The below-given figure helps you visualize the same. The length of the rope that wraps around the circle's boundary perfectly will be equal to its circumference. This means that the perimeter of a circle is also referred to as its circumference. If the diameter of a circle is known, its radius can be calculated as: r = d/2 or R = D/2.Ĭircumference: The circumference of the circle is equal to the length of its boundary. ![]() It is represented by the letter 'd' or 'D'.ĭiameter formula: The diameter formula of a circle is twice its radius. Radius plays an important role in the formula for the area and circumference of a circle, which we will learn later.ĭiameter: A line that passes through the center and its endpoints lie on the circle is called the diameter of a circle. It is represented by the letter 'r' or 'R'. Radius: The distance from the center to a point on the boundary is called the radius of a circle. The measure of the space or region enclosed inside the circle is known as the area of the circle. We see circles in everyday life such as a wheel, pizzas, a circular ground, etc. A circle is a collection of points that are at a fixed distance from the center of the circle. Let us recall the circle and its parts before learning about area of circle in detail. 1.ĭifferences Between Area and Circumference of a Circle Let us learn in detail about the area of a circle, surface area, and its circumference with examples. A circle only has an area and perimeter/circumference. A circle is a two-dimensional shape, it does not have volume. Does a circle have volume? No, a circle doesn't have a volume. Suppose, if you have a circular table, then the area formula will help us to know how much cloth is needed to cover it completely. The area of a circle formula is useful for measuring the region occupied by a circular field or a plot. The unit of area is the square unit, for example, m 2, cm 2, in 2, etc. The formula for the area of a circle is A = πr 2, where r is the radius of the circle. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. ♬ original sound – Mometrix Test the formula for volume of a cylinder!

Sticking with the construction theme, surface area is important when determining the amount of tile to put on a rectangular floor, of wallpaper on a wall or the amount of paint needed to cover the total surface of a building.Īll of these calculations can be done manually, but in the real world, time is of the essence when completing a project. Generally concrete slabs are rectangular solids, so the rectangular prism calculator can be used. One such instance is in road or pavement construction where slabs of concrete must be built. There are many applications in real life where the volume calculator is useful. It’s very important in terms of architecture and construction One might wonder where this calculator will be useful in a real-life setting. Using these formulas manually won’t be difficult, but for fast, accurate results every time, use the volume calculator.Ĭone = \((\frac(4)=12\pi\) cubic centimeters Knowing the definition of volume, we can now focus on the formulas for volume of common geometric solids. Volume is the amount of total space on the interior of the solid. Volume calculator will determine the volume of the most common geometric solids. ![]()
