The area of a circle is 706.5 what is the radius?

15units

Step-by-step explanation:

Area=pi×r², where r is the radius.

706.5=3.14×r²

r²=225

r=15units

r = 15 units

Step-by-step explanation:

hello :

The area of a circle is : A= πr²   r is the radius

πr² = 706.5

r² = 706.5/3.14 = 225

r² = 15²

so  :   r = 15 units

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
