circumference = 2*pi*15.8 = 99.27432785 or 99.274 cm to 3 d.p.
The radius of a circumference is half of the diameter. To find the radius of a circumference with a length of 64cm, you need to divide the circumference by 2π (since the formula for the circumference of a circle is C = 2πr). So, the radius would be 64cm / (2π) ≈ 10.19 cm.
Circumference = pi*15.5 = 48.695 cm rounded to 3 dp
Circumference of circle: 2*pi*4.9 = 30.788 rounded to 3 decimal places
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
radius = 17/(2*pi) = 2.705634033 or 2.706 cm to 3 d.p.
circumference = 2pi4.2 = 26.389 cm to 3 decimal places
Circumference = 2*pi*radius (not raduis) = 19 cm, approx.
About 18.85cm
The circumference of a circle with a radius of 3.2 cm is approximately 20.1 cm. This can be calculated using the formula: circumference = 2 * π * radius.
Circumference = 2*pi*7.1 = 44.611 cm and rounded to 3 dp
radius = 28.6/2*pi = 4.552 cm rounded to 3 dp
circumference = 2pi50 = 314.159 cm to 3 decimal places
