Sorry for the hand writing. But you want to factor out a 4y^2 which will result in (9y^2-1). Then you will factor out the equation in parentheses to (3y-1)(3y+1). Don’t forget to put the 4y^2 out front!

The area of a circle is 201 cm². What is the diameter

natima [27]

Answer:

The diameter would be 16

Step-by-step explanation:

The area of a circle is a= $r^{2}$ ×π. Now just plug in the values you have which is you area. 201= $r^{2}$ ×π now divide by pi on both sides you that you get about 64= $r^{2}$ . Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16
