Answer:

9852 Rounded to the nearest whole number.

Step-by-step explanation:

C = 2 $\pi$ r Fill in what we know to solve for r

176 = 2 $\pi$ r Divide both side by 2 $\pi$

r = 28 rounded to the nearest whole number.

The formula for the area of a circle is

A = 4 $\pi$ $r^{2}$

A = 4 $\pi$ $28^{2}$

A = 9852 Rounded to the nearest whole number

Step-by-step explanation:

I will assume that you're trying to solve for "x".

For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.

Now, 131 = 5x+1

-1 -1

130 = 5x

/5 /5

Now, we isolate the x to get x=26.

Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.

Now, combine the like terms to get 11x+15=180 so we now isolate x.

-15 -15

11x=165

/11 /11

x=15

Now, try the rest and set the terms to 180.

5x+1+8+4x=180

2x+1+x-10=180

6+x+5x=180

x+2+153=180(This is similar to #1)

The correct answer is the 2nd choice because -1/6 is closer to 0 and the surface of the pool would be considered 0. -4/6 is farther away from 0 so it is less.
