What is the formula for finding the circumstance for a circle with just the radius?

The answer is the red square, 2* pi* r

Step-by-step explanation:

In order to find the circumference* of a circle, you need the radius to be multiplied with pi and 2

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
