Hello.
Plug in the value of p:

Now, all we have to do is solve the equation for y.
First, let's add 10 to both sides:


Now, add 3y to both sides:

Divide both sides by 3:

I hope it helps.
Have a nice day.

Answer:
48??
Step-by-step explanation:
We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
1225*(1.578*10^-5)=1.933*10^-2
1.578*10^-5= 0.00001578
1225*0.00001578=0.0193305
0.0193305=1.933*10^-2
