Write in standard form:

4r^2 = 9


Answer :

Answer:

0.75 or 3/4 = r

Step-by-step explanation:

To figure out the value of r, you must find the square root of both sides, which would cancel the square. Now the equation would be 4r = 3. From there, you can divide both sides by 4 to get r by itself. so now, the equation is r=3/4 or 0.75
