Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699
Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches
If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
Circumference of a circle = 2*pi*radius or diameter*pi
The circumference of a 12 cm circle is: 37.7 cm
The radius of a circle with a circumference of 12 is: 1.91
Its radius will be 76/2*pi which is about 12 inches rounded to the nearest integer
The area of a circle with a 12-foot circumference is about 11.46 square feet.
diameter = circumference/pi = 12/pi inches
Assuming the '12 inch' is the radius. Then C = 2 pi r C = 2 pi 12 C = 24 pi ( Thr asnswer in terms of 'pi').
well the formula is 2 pie r
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
Circumference = 37.7 inches Diameter = 12 inches
Circumference of a circle = 2*pi*radius or pi*diameter
A 12-inch diameter circle has a circumference of: 37.7
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
12 inch diameter(also 6 inch radius).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).Circumference of a circle is pi x diameter, pi has a value of 3.1415, can you proceed from here, you can do it, try it, Good luck!
12 inch diameter(also 6 inch radius).
Circumference of a 25 feet circle = pie x diameter x 12 942.477 inch 1 feet = 12 inch so i converted into inch as i am having the other component in inch No of 12 inch long blocks = circumference /12 so total 78 pieces will be required to make a circle of dia 25 feet
