Well, we know that if a circle has a diameter of 1, the circumference is pi, and we also know that the radius is 1/2 of the diameter, so we multiply the radius (56) by 2 to get 112, which we multiply by pi to get the circumference. So, we could either assume pi is 3.1415926, or we could express this number as 112π units, or as 351.858371 units.
The radius is 1/2 the diameter. So, 56 / 2 = 28 radius.
Radius is 8.912
diameter = 2 × radius Area_circle = π × radius² → radius = √(area_circle ÷ π) → diameter = 2 × √(area_circle ÷ π) = 2 × √(56 units² ÷ π) ≈ 8.444 units.
A = 9,852 units2
circumference:diameter = pi (about 3.14...)
The radius is 1/2 the diameter. So, 56 / 2 = 28 radius.
Radius is 8.912
If the circumference of a circle is 351.68 the radius is: 56
The formula for the circumference of a circle is C = pi r2 where r is the radius. Substituting 56 inches for the radius gives: C = pi(56)2 = (3136)pi inches.
diameter = 2 × radius Area_circle = π × radius² → radius = √(area_circle ÷ π) → diameter = 2 × √(area_circle ÷ π) = 2 × √(56 units² ÷ π) ≈ 8.444 units.
It means the distance around a circle
72.22
A = 9,852 units2
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
Circumference = pi*d where d is the diameter.
