8^(1/3) + 8^0  =    2  + 1  = 3

4.24725201905  x 10^21      Wow!

S.O.S.......Here ya go !

$40 x = $100 + $20 x

20x=100

x=5 weeks  they will equal

Pi is just used as one of the factors that make up the number...

example:   Circumference of circle with 10 inch diameter    circ = pi x d  

                    the circumference would be expressed as  10 pi    (which means 10 x pi)

Basically ....you just leave 'pi' in the calculations and result rather than substituting in 3.14156 and multiplying it out.

Circumference = pi x d  =  pi x 12.6(2) = 25.2 pi

Fraction of circumference of the central angle arc

2pi/7  / 2pi

2pi/7  /  2pi   x 25.2 pi = 1/7 * 25.2 pi = 11.30 ft

I will assume it is a CUBIC container with 9 cm sides

Volume = area x height

             = (9x9) x 2/3(9) = 81 x 6 = 486 cm^3 = 486 ml

3 ft 10 in = 2 ft 22 inches

2 ft 22 inches - 11 inches = 2ft 11 inches

(400)/ [(400^2 - (400-20)(400+20) ] =

400(400^2 -400^2 +20^2) =

400/(20^2)

400/400 = 1     No calculator required !
