5.86 cm.

Step-by-step explanation:

First, we can find the area of the circle:

π · 1² = 1π or just π.

Next, we can find the area of the rectangle without the circle:

3cm · 3cm = 9cm total for our area. (without circle inside).

Now we can subtract pi from our answer 9 cm.

That gives us 5.85840734641

Since this once it to the nearest hundredth, we round:

5.86 because 8 is our determining digit.

So 5.86 is our answer

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
