The answer is 32 because you have to the inverse operation so you divide 320 by 2 you get 160. Then you divide 160 by 5a then you have a=32. To check you substitute: 5(32)2=320.

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
