The radius of a circle is 5 inches What is the circumference of the circle?
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
Is the circumference greater than the diameter?
No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.
What is the radius If the circumference is 96.5?
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
How do you find the diameter of a cylinder from the area of the base?
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.
What is sin of 3 pi over 2?
sin pi/2 =1 sin 3 pi/2 is negative 1 ( it is in 3rd quadrant where sin is negative
What is pi times x over 2 divided by 2?
4
What is 2 pi over 2?
2 pi / 2 = pi.
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
What is pi times pi equal?
pi^2
What is 4 times pi times pi times 4 divided by 2?
4 times pi times 4 divided by 2 is 78.9568352087
How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
Is circumfrience pi times radius to the 2?
circumfrience is pi times radius to the 2 i think
What is Pi 1 times 1 times 2 divided by 3?
It is 2*pi/3.
What is the reciprocal of pi over two?
(pi/2)-1 = 2/pi
What does pi radius 2 mean?
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.
Is circumference radius times pi?
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.
