How many ways can the letters of the word organism be arranged so that the third letter is g

5040

Step-by-step explanation:

"organism" has 8 letters. Since the g is not to be permutated, let's take it out, and we're left with 7 letters.

For the first position we have 7 options. For the second position we have 6 options, etc., so 7*6*5*4*3*2*1 = 7! = 5040.

The "g" we just insert at the 3rd position, it doesn't play any role in the counting.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
