The formula for circumference is 2(pi)r, so first you would divide by 2, which is 56.52 (about) then divide by pi and you get 18. So the radius is 18, so multiply 18 by 2 and you get 36.
So therefore, the diameter is 36 inches
Answer:
5:3
Step-by-step explanation:
100: 60
Divide each side by 20
100/20 : 60/20
5:3
In this question , we have the formula of acceleration given, which is

And we have to solve for 
First we need to get rid of denominator t from right side and for that, we multiply both sides by t, that is

Now to solve for v1 , we need to get rid of v0, and for that , we add v0 to both sides, that is

And that's the required answer.
The correct answer is 60 cm
