Area Of Circle Definition Formula Examples Chilimath The formulas are used based on whether the radius, diameter, or circumference is known to us. each of the three situations is discussed below with their formulas and solved examples. how to find the area of a circle using the radius. when the radius of a circle is known, the formula to determine the area is given below:. Solved examples on area of a circle. example 1: if the diameter of a circular garden is 50 feet, find the area of the garden. solution: diameter of the circular garden (d) = 50 feet. the radius of the circular garden (r) = d 2 = 25 feet. the area of the circular garden (a) = πr 2. a = π (25) 2. a = 625π square feet.

Area Of A Circle Formula Examples Curvebreakers Finding the diameter of a circle using its area. example 9: determine the diameter of a circle with an area of [latex]18.27[ latex] square meters [latex]{m^2}[ latex]. note: use [latex]\pi = 3.1416[ latex] and round your answer to two decimal places. we can use the formula the area of a circle wherein the input value is the diameter. Area of a circle is the region occupied by the circle in a two dimensional plane. it can be determined easily using a formula, a = πr2, (pi r squared) where r is the radius of the circle. the unit of area is the square unit, such as m2, cm2, etc. area of circle = πr2 or πd2 4, square units. where π = 22 7 or 3.14. Examples of finding the area of a circle. we will use the following formula to find the area of any circle. notice that this formula uses the radius, so we will have to convert when we are given the diameter instead. let’s look at both cases. example (given radius) find the area of a circle with a radius of 5 meters. solution. apply the. Area of a circle, a = πr 2 square units. circumference perimeter = 2πr units. area of a circle can be calculated by using the formulas: area = π × r 2, where 'r' is the radius. area = (π 4) × d 2, where 'd' is the diameter. area = c 2 4π, where 'c' is the circumference (sometimes referred to as perimeter).

How to calculate the area. the area of a circle is: π ( pi) times the radius squared: a = π r2. or, when you know the diameter: a = (π 4) × d2. or, when you know the circumference: a = c2 4π. example: what is the area of a circle with radius of 3 m ?. The area of a circle is known as the range covered by a circle in a 2d plane. in basic terms, the area of a circle is the area covered by a circle inside its boundary or circumference. here, a = area of a circle is ; r = radius of a circle ; π = represents the pi which is constant. formulas for the area of a circle. formulas for the area of a.
