Find radius of cylinder if height equals 36cm and volume equals 2826?
volume = p*radius2*height make the radius the subject of the formula: radius = the square root of (volume/pi*height) radius = the square root of (2826/pi*36) radius = 4.998732446cm So the radius is 5cm to the nearest cm.
What is 2826 to the nearest hundredths?
2826.00 (if you wish to indicate the precision). Otherwise, stick with 2826.
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
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 the radius of a circle with an area of 2826?
the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)

How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)

Why is circumference equal to 2 times Pi times r?
Circumference = pi times diameter or Circumference= two x pi x radius. Now remember the diameter of a circle is the straight line from one edge of the circle, through the centre to the opposite edge. The straight line from the edge to the centre is the radius, and then from the centre to the opposite edge is another radius. So the diameter is the length of two radii. Algebraically express as d = 2r. So Algebraically C = pi*d Substituting the 'd' for '2r' C = pi2r However in algebra coefficient numbers are expressed to the left. Hence C = 2pir Why 'C' is this expression I would have to go into some 'very heavy' differential calculus. Suffice it to say, the ancients found that the circumference traced by a donkey/mule driving water out of well was directly proportional to the diameter, twice the length of the tether(2 radii). From this they discovered that for however long the the tether and the circumference were. they had a constant of proportion C directly related to diameter. This is equated to C = kd And k = C/d , which was founf to be 3.141592..... which now call 'pi'. for any sized circle. So today in school you learn C = pi d or C = 2 pi r And for circular area(A) A = pi r^(2) The 'pi' youare given in school is proabably 3.14 , 3.1416 or 22/7 . However, these values are Approximatons, because 'pi' is an irrational number. Hope that helps!!!!!!
