WebThis formula says that to find the diameter, we must take the circumference and divide it by Pi (3.14) d = 6.28 ÷ 3.14. On simplifying we get : d = 2 meters. Now, as we know the diameter, it is easy to find the radius. The diameter is twice as long as the radius, so the radius is half as long as the diameter. 2 ÷ 2 = 1. So, the radius is 1 ... WebMar 27, 2024 · Diameter and circumference are lengths related to each other — the higher the diameter, the higher the circumference. The circumference to diameter formula connects these variables in a single equation: c = πd, where: c stands for the circumference; d for the diameter; and π is the pi number.

WebFeb 28, 2024 · Mathematically, Diameter=2×radius. When the diameter of a circle is provided then the radius formula: R (Radius) = Diameter 2 or D 2 units Radius using Circumference of Circle The circumference of a circle is the total extent of the boundary of the circle. The circumference of a circle is also known as the perimeter of the circle. WebExample 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference. Circumference = πd = 3.14159 × 12 = 37.69 feet. round trip to paris france
