The square root of 40 is 6.33
Answer:
Standard form: 
Center: 
Radius:
Step-by-step explanation:
The equation of a circle in the standard form is

Where the point (h, k) is the center of the circle
To transform this equation
this equation in the standard form we use the method of square.
First, we group similar variables

Divide both sides of equality by 4

Now we complete square for variable x.
Take the coefficient "b" that accompanies the variable x and divide by 2. Then, elevate the result to the square:

Now add
on both sides of the equality

Factor the expression and simplify the independent terms


Then

and the center is 
radius
First, you need to make sure that they're in the same measurement ration
1 m = 100 cm
so, now you have
73 cm + 160 cm + 287 cm + 325 cm + 404 cm
The total length would of all the wood would be be 1249 centimeters or 12.49 meter
60% of 90 is 54 by doing 90*60/100
2/3 of 150 is 100 because 150 divided by 3 times 2 is 100
and dawn sold 46 cookies.
if you add all the cookies sold up, you get 200 cookies.
Dawn having sold 46 cookies out of the 200, if you want to have a percentage, you have to change that 200 which is the total into 100.
So 200/2=100 and 46/2=23
Dawn sold 23 cookies for every 100 cookies sold so 23%
Yes he is correct because a horizontal line goes straight across
