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)

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.

11,305 ÷ 4 = 2826 with remainder 1 OR 2,826.25 times.

the same as pi squared, which is 9.86960440109

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)

2826.00 (if you wish to indicate the precision). Otherwise, stick with 2826.

C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter

Area=pi times radius squared Circumference=pi times diameter or pi times radius times two

circumference=pi circumference=pi circumference=pi

pi^2

2826

area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
