Question

Circumstance of 12yd

Answer 1

Answer: 40.82yd

Step-by-step explanation:

First of all, it's ''circumference'' and second of all, it's ''13yd''.

$Formula: C=2\pi r$

2r is the same as d = diameter,

$C=\pi d$

$C=(3.14)(13)\\C=40.82yd$

Answer 2

Answer:

See answer below

Step-by-step explanation:

Hi there,

Please recall the circumference formula:

$C = 2\pi r$  where $\pi$ = 3.14159... the irrational constant and r is the radius of the circle.

The dotted line across the circle cuts through its center, from one end point to the other, the definition of the diameter...

Since the diameter is related to radius, we can calculate the circumference as follows:

$r=\frac{d}{2}$    $C = 2\pi (\frac{d}{2})^ = 2\frac{\pi d }{2} = \pi *d = \pi * (13 \ yd) = 40.84 yd$

Hence we obtain a circumference length of 40.84 yards. Study well and persevere.

thanks,
