The radius of a circle is half of the diameter, so if
the diameter is 56cm the radius can only be 28cm.
The radius is 1/2 the diameter. So, 56 / 2 = 28 radius.
diameter = 2 × radius Area_circle = π × radius² → radius = √(area_circle ÷ π) → diameter = 2 × √(area_circle ÷ π) = 2 × √(56 units² ÷ π) ≈ 8.444 units.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Radius is 8.912
A circle's circumference equals PI times the circle's diameter. So, to find the circumference of a circle with a diameter of 56 we do the following:3.14159x 56___________________________175.92919YOUR ANSWER IS 176 (rounded)
The radius is 1/2 the diameter. So, 56 / 2 = 28 radius.
72.22
diameter = 2 × radius Area_circle = π × radius² → radius = √(area_circle ÷ π) → diameter = 2 × √(area_circle ÷ π) = 2 × √(56 units² ÷ π) ≈ 8.444 units.
Circumference of a circle: 2*pi*radius or pi*diameter
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Diameter equal 2r (d=2r) So if your Diameter is 28 then: 28=2r (divide 2 on both sides) 14=r therefor the radius is 14
Radius is 8.912
A circle's circumference equals PI times the circle's diameter. So, to find the circumference of a circle with a diameter of 56 we do the following:3.14159x 56___________________________175.92919YOUR ANSWER IS 176 (rounded)
If the circumference of a circle is 351.68 the radius is: 56
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.
Circumference of the circle: 56*pi = 175.929 cm
A = 9,852 units2
