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').
Since a complete circle is 360 degrees, a 30-degree part of a circle is 30/360, or 1/12, of the pie.
12.0 if you want 3 sig-figs, or 12 if you only want 2.
To determine how many 12-inch rulers would be about the same length as a flag, we first need to know the dimensions of the flag in question. For example, a standard flag might be 3 feet long, which equals 36 inches. In this case, you would need 3 rulers (36 inches ÷ 12 inches per ruler = 3 rulers) to match the flag's length. Adjust the calculation based on the actual length of the flag you are considering.
The maximum angle for a handicap ramp is typically 1:12, meaning for every inch of rise, there should be at least 12 inches of run. This translates to an angle of about 4.76 degrees. In some cases, steeper ramps may be allowed, but these should only be used for short distances and with proper safety measures in place. Always check local building codes for specific regulations.
Sin(10)*12 = 12*sin(10) = 12*0.1736 = 2.0838, approx.
diameter = circumference/pi = 12/pi inches
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
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 pi*diameter
A 12-inch diameter circle has a circumference of: 37.7
12 inch diameter(also 6 inch radius).
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.
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a 12-inch radius, the circumference would be ( C = 2\pi \times 12 ), which equals ( 24\pi ) inches. Approximating ( \pi ) as 3.14, the circumference is approximately 75.4 inches.
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).
