To find the circumference of a circle you have to multiple the radius by 2 and also by pi. So, to find the radius when given just the circumference, who have to do the reverse operation and divide the circumference by 2 and also by pi to get the answer of 22.92993631, which you could of course round.

SVETLANKA909090 [29]

Answer:

\frac{-5}{3}

Step-by-step explanation:

3(2 + 4x) = -7 x 2  Distribute the 3

6 + 12x  = -14  Subtract 6 from both sides of the equation

12x = -20  Divide both sides by 12

x = \frac{-20}{12}  Divide the top and the bottom of the fraction by 4

x = \frac{-5}{3}

Diff Eq dy/dx= (ycos(x))/(1+y^2) initial condition is y(0)=1 work below ...?
Volgvan
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2
