Area of a quarter circle = 1/4 * pi * r^2

 = 1/4 * pi * 4^2    =   12.6 m  to 3 sig figs.

perimeter = 4 + 4 + 1/4 * 2 pi * 4 =  14.3 to 3 sig figs.

The following table shows a proportional relationship between mmm and nnn.
Marina CMI [18]

Answer:

70707mmm = 111nnn

Step-by-step explanation:

Using the basic equation of a line:

y = mx + c;. where m is slope and c is intercept on y axis.

Let mmm = y and nnn = x

(i) 333 = 212121m + c

(ii) 555 = 353535m + c

Making c the subject of the formula in both (i) and (ii)

c = 333 - 212121m = 555 - 353535m

353535m -212121m = 555 - 333

141414m = 222

m = 111/70707

Substitute in (i) above

c = 333 -333 = 0

Hence; y = 111/70707x + c

Finally, mmm = 111/70707 nnn

i.e. 70707mmm = 111nnn

Hope this helps.
