How many distinct 9-letter words starting with “i” can be formed from the word “committee”?

5040

Step-by-step explanation:

Step 1:

Distinct 9-letter words formed from the word "COMMITTEE" is equal to the number of different permutations for word "COMMITTEE".

Step 2:

Now, if in the 9-letter word the  first letter is fixed as "i". Then  number of distinct words formed will be equal to number of different permutation for the word "COMMTTEE".

Step 3:

Now, the as it is known that number of permutation of n distinct object where p, q and r distinct object are of the same kind is equal to .

Therefore,

Number permutation for the word "COMMTTEE" will be equal to  .

Now,

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m
