The circumference of the circle is 28.26 in.

Step-by-step explanation:

Given,

The diameter of a circle = 9 in

Radius of the circle (r) = 4.5 in

To find the circumference of the circle.

Formula

The circumference of the circle of radius r = 2πr

Now,

The circumference of the circle = 2×3.14×4.5 in [ taking π = 3.14]

= 28.26 in

Can someone help me please
Neporo4naja [7]

If Deliah does jumping jacks at a constant rate, this means that she does them at the same pace or you could say that she does the same amount of jumping jacks in a specified amount of time, ie. if you counted how many jumping jacks she did in one minute, it would be same as how many she would complete in the next minute, and the next, and so on.

Now given that she does 184 jumping jacks in four minutes, and she has kept a constant pace throughout, to find out how many she does each minute, we simply need to divide the number of jumping jacks she does in 4 minutes by 4. Thus:

Jumping jacks in 1 minute = Jumping jacks in 4 minutes / 4

= 184 / 4

= 46

Thus, Deliah can do 46 jumping jacks per minute.
