2*pi*31 square mm or pi*62 square mm
Circumference = 2 * Pi * rr(radius) = diameter/2 = 31/2 = 15.5Circumference = 2 * pi * 15.5= 97.4 units==========( you could call it 97 units )
radius of 31 inches
if the circumference is 31 inches you know that... Diameter = circumference/(pi) D = 31in/3.1 D=10 r= 1/2D r=1/2(10) r=5
A circle with a radius of 31 cm has an area of 3019.07 square cm.
Circumference of a circle = (pi) x DiameterDiameter = 2 x radiusCircumference = (pi) x (2 x radius)(2 x radius) = Circumference/piRadius = Circumference/(2 x pi) ==> Over to you.
31 feet 5 inches
I'm not sure what you mean. If the radius is 5, the circumference is 10pi. (about 31 and a half) If the circumference is 5, the radius is 5 divided by 2pi. (about four fifths)
2*pi*31 square mm or pi*62 square mm
Circumference = 2 * Pi * rr(radius) = diameter/2 = 31/2 = 15.5Circumference = 2 * pi * 15.5= 97.4 units==========( you could call it 97 units )
radius of 31 inches
Improved Answer:-Its radius: circumference/diameter = piIts area: pi*pi squared = 31 square cm rounded to nearest integer
if the circumference is 31 inches you know that... Diameter = circumference/(pi) D = 31in/3.1 D=10 r= 1/2D r=1/2(10) r=5
Circumference of circle: 31*pi = 97.389 inches rounded to 3 decimal places
31x3.1416=circumference
A circle with a radius of 31 cm has an area of 3019.07 square cm.
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
