remember the formula for circumference -> pi x d where pi is our favorite number in math i.e. 3.14159.... and d is the diameter. So your answer would be
3.14159 x 31 = 97.39 (rounded to decimal places) but your 31 should also have a unit of length with it.
To find the diameter from the circumference, you can use the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Rearranging the formula gives ( d = \frac{C}{\pi} ). For a circumference of 31 inches, the diameter is approximately ( \frac{31}{3.14} ), which is about 9.87 inches.
31 feet 5 inches
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. Given that the diameter is 31 mm, the circumference would be ( C = \pi \times 31 \approx 97.39 ) mm (using ( \pi \approx 3.14 )). Therefore, the circumference of the circle is approximately 97.39 mm.
diameter = circumference/pi
Circumference = 2 * Pi * rr(radius) = diameter/2 = 31/2 = 15.5Circumference = 2 * pi * 15.5= 97.4 units==========( you could call it 97 units )
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
To find the diameter from the circumference, you can use the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Rearranging the formula gives ( d = \frac{C}{\pi} ). For a circumference of 31 inches, the diameter is approximately ( \frac{31}{3.14} ), which is about 9.87 inches.
31x3.1416=circumference
Circumference of circle: 31*pi = 97.389 inches rounded to 3 decimal places
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
31 feet 5 inches
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. Given that the diameter is 31 mm, the circumference would be ( C = \pi \times 31 \approx 97.39 ) mm (using ( \pi \approx 3.14 )). Therefore, the circumference of the circle is approximately 97.39 mm.
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
diameter = circumference/pi
Circumference = 2 * Pi * rr(radius) = diameter/2 = 31/2 = 15.5Circumference = 2 * pi * 15.5= 97.4 units==========( you could call it 97 units )
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
