Answer:

29.52 meters

Explanation:

The equation to find the circumference of a circle is:


2\pi{r}

but the problem requires you to replace π with 3.14

In able to find the radius from the diameter you need to divide it by two: r=d/2

So first identify needed needed numbers.

d=9.4

π=3.14

Second, find radius.

9.4/2=4.7

Then solve using given equation.

2•3.14•4.7=29.516

Finally, round to the nearest hundredth.

29.52

Therefore the circumference of the circle is 29.52 meters.

Answer:

the answer is

Explanation:

Circumference=2πr or πd

Since it is a diameter use the formula πd

d=9.4 meters

π=3.14

=3.14×9.4=29.51600 or 29.516

To the nearest hundredth, you round up the next number after the hundredth and it is 6 so you round up 6 and it becomes 1

Then you add 1 to the hundredth which is 1

Therefore, to the nearest hundredth=29.520 or 29.52meters.
