Hi all,

Our wonderful answer were provided by Geno3141, Jillybean, Radix and Heureka.  Thank you.

Arc length = (22/360) * 2pi*r

$${\frac{{\mathtt{22}}}{{\mathtt{230}}}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{18}} = {\mathtt{10.818\: \!006\: \!007\: \!143\: \!983\: \!7}}$$

Oh you wanted the exact length  :/

22 degrees = 22*pi/180 radians

    $$\\Arc\;\;length\\\\
=\frac{22\pi}{180}*2*\pi*18\\\\
=\left[\frac{22\pi}{180}\div (2\pi)\right]*2*\pi*18\\\\
=\left[\frac{22\pi}{180}\times \frac{1}{ (2\pi)}\right]*2*\pi*18\\\\
=\left[\frac{11}{180}\right]*2*\pi*18\\\\
=\frac{11\pi}{5}\;\micro \mu m\\$$

OR

The highest common factor of 60, 105 and 75 is 15

so you could have 15 baskets each with 4 pears, 7 bananas and 5 apples

She has 240 peices of fruit so she could have 240 baskets  with one peice  of fruit in each basket.

Good thinking Radix.   

I would like to see a proof though.  :/

Thanks Heureka, I did miss that one.   

I don't actually understand what you have done :/

$${\mathtt{141.08}}{\mathtt{\,\times\,}}{\mathtt{50}} = {\mathtt{7\,054}}$$

7054 p    and I think that is 70.54 pounds

It is easier if you change all the units to metres first.

0.5*0.5   m^2 each tile

Total = 0.5*0.5*108

$${\mathtt{0.5}}{\mathtt{\,\times\,}}{\mathtt{0.5}}{\mathtt{\,\times\,}}{\mathtt{108}} = {\mathtt{27}}$$

27 m^2
