Three city commissioners can be selected from a group of ten candidates in how many different ways

There are 10 ways you can pic the first, 9 ways to pick second, and 8 left to pick the third so there are a total of 10•9•8= 720 ways

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

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
