As you know that diameter is the chord of the circle which passes through its center and its the longest chord of the circle too. So from both examples given above, we concluded that area is same whether you use the formula in the form of radius or diameter. Required fields are marked *. 0. A = π x (ø/ 2) 2 Diameter of Circle. Usually, the formula of a circle is used in the promptitude of a radius. Everyone has one strong driving force in self that let one evolve above boundaries, my passion is content creation. The diameter will always pass through the center of the circle. So, for the area of a circle given diameter, use this formula: Area of a circle = π × (D × 1 / 2) 2. Formula of area of circle in the form of diameter is Area = pi * (diameter/2)* (diameter/2) Area = (1/4)* pi * d2 For the sake of understanding, we will solve the … Area =? If you know the radius, r, in whatever measurement units (mm, cm, m, inches, … We suggest to use the same formula to find the area of a circle which uses radius in it. The "time complexity" of this algorithm is O(n). If you have the diameter of a circle, you can use it to find the area of that circle. The Area and perimeter of a circle work with steps shows the complete step-by-step calculation for finding the circumference and area of the circle with the radius length of $8\;in$ using the circumference and area formulas. If you'd like to calculate the area of a circle from the diameter, you have to know what a diameter is. Area of circle A= πr 2 = π10 2 = 100π. Diameter of Circle This is the diameter of a circle that corresponds to the specified area. Finding the radius, diameter, area and circumference of a circle [duplicate] Ask Question Asked 5 years, 11 months ago. Find the radius, circumference, and area of a circle if its diameter is equal to 10 feet in length. 1 answer. Hence, you can just find the radius when the area of a circle is given and then multiply your result by 2 to get the diameter. on How To Calculate The Area Of Circle If Diameter Is Given? This calculator will calculate the area of a circle given its diameter, using the famous formula area = pi times (d/2) squared. Perimeter of Semi-Circle . // C Program to calculate area of a circle #include
