Find the area of a circle with a radius of \color{purple}{2}2start color purple, 2, end color purple.

liraira [26]

Answer:

Maybe 12.56

Step-by-step explanation:

Well, the question is a bit hard to read, but I assume the radius is equal to 2?

The formula for the area of a circle is п*r*r

The number п is equal to 3.14

so п*2*2 = 3.14*4 = 12.56

Though if the radius is not 2, try to use that formula and if you cant get it please let me know in the comments

omeli [17]

Answer:

There are 286 possible combinations

Step-by-step explanation:

To solve this problem we must use the formula of combinations.

$nCr =\frac{n!}{r!(n-r)!}$

Where n is the number of players that there are and elect r of them

In this case there are 7 + 6 = 13 players and you choose 10 of them

Then we look for 13C10

$13C10 =\frac{13!}{10!(13-10)!}$

$13C10 =\frac{13!}{10!*3!}$

$13C10 =286$

There are 286 possible combinations
