Circle o has a circumference of approximately 44in. what is the approximate length of the diameter d? 7 in 14 in 22 in 44 in

The distance around a rectangle or a square is as you might remember called the perimeter.

The distance around a circle on the other hand is called the circumference. It is calculated as follows:

C = 2pi(r)

From this, we can solve for r and eventually solve for the diameter.

44 = 2pi(r)

 r  ≈7.00

d = 2r

d = 142answers

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
