Pi. The twos cancel each other out.
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
sin(pi/4) and cos(pi/4) are both the same. They both equal (√2)/2≈0.7071■

2 pi / 2 = pi.
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
pi^2
4 times pi times 4 divided by 2 is 78.9568352087
2 x pi x 2 = 4 x pi
(pi/2)-1 = 2/pi
circumfrience is pi times radius to the 2 i think
It is 2*pi/3.
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
