Answer:

Circumference = 56.52 \cm\\\\Area = 254.34 \ cm^2

Step-by-step explanation:

Taking π = 3.14

Circumference = 2 \pi r= 2 \pi \times 9 = 18 \pi = 18 \times 3.14 = 56.52 \ cm\\\\Area = \pi r^2 = \pi 9^2 = 81 \pi  = 81 \times 3.14 =  254.34 \ cm^2

What is 2 plus 2 plus 3 times 3
guajiro [1.7K]
So, in order, you have to multiply first. 3x3=9, now you have to do 2+2=4. Since there is a "plus" in between "2+2" and "3x3" you have to add, 9+4=13.

Round the fraction 7 4/5 to the nearest whole number
Over [174]
Im not sure if you are saying 74/5 or 7 and 4 fifths but in the case you'r saying 74/5 you would first round to see the highest number that 5 can go to without being a decimal. Which would be 70 so you would count how many times 5 can go into 70, which would be 14, so the left over is 4/5 so you would check to see if it can be simplified which it can't so the final answer is 14 and 4/5

babymother [125]

Answer:

\Huge\boxed{\mathsf{\longrightarrow N=-7}}}

Step-by-step explanation:

Isolate by the n on one side of the equation.

First, switch sides.

n+36.2=29.2

Then, subtract 36.2 from both sides.

n+36.2-36.2=29.2-36.2

Solve.

36.2-29.2=-7

<u>n=-7</u>

<u></u>

The correct answer is n=-7.
