It's C. In order to be in standard form you have to have all your exponents in descending order. They don't all have to be there in order, the ones that are just have to go from highest to lowest.
2r+7+2n+n2
Because I combined the ones with like terms.
The answer is 3.2
hope it helps ya
Just do circumference over pi (this'll give you the diameter) and then divide by 2 to get radius like so:
44/pi=14.0056349921/2=7.0028175 is your answer
îdk how you wanna round but nearest hundredth would be 7.00 cm while nearest tenth would be 7.0 cm and nearest whole number would be 7 cm
