A. 114 cm^3
b. 155 cm^3
c. 283 cm^3
d. 303 cm^3

Hey there :)

We apply the same rules as we did to the previous questions

V (big cylinder) = 
2264 = 
283 = 


r ≈ 9.49 cm

The ratio from the big cylinder to the small is:
8 : 4
 
Therefore, the big cylinder is 2 times the small cylinder

= r
r ≈ 4.75 (radius of small cylinder)

V(small cylinder) = 
                            = 283 cm³

Your answer is option C. 283 cm³

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
