How many different "words" can be made from the given word by re-arranging the letters? 1. KINDNESS 2. MATHEMATICIAN

Step-by-step explanation:

Permutation has to do with arrangement.

To form different word by rearranging the word KINDNESS, this can be done in the following way;

The total letters present in kindness = 8 letters

Repeated letters are 2N's and 2S's

The arrangement is done in ways

For MATHEMATICIAN;

The total letters present in kindness = 13 letters

Repeated letters are 2M's, 2T'S 2I'sand 3A's

The number of words formed =

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
