The inner circumference of a circular race track, 14 m wide, is 440 m. Find radius of the outer circle
Let inner radius be r metres. Then, 2πr = 440 ; r = 440×744= 70 m.
Radius of outer circle = (70 + 14) m = 84 m.

Based on these statements which of the following conclusions is true?
Find the odd word/letters/number from the given alternatives.
Find the number of zeroes in 129!
Select the figure that does NOT belong in the following group.
If the mean of a, b, c is M and ab + bc + ca = 0, then the mean of a2+b2+c23 is :
We have : ( a + b + c) / 3 = M or (a + b + c) = 3M.
Now. a+b+c2=3M2=9M2 .
<=>a2+b2+c2+2ab+bc+ca=9M2
a2+b2+c2=9M2 ,(ab+bc+ca=0)
Required mean =a2+b2+c23=9M23=3M2 .
