The main tank at an aquarium is a cylinder with a diameter of 203 ft and a height of 4 ft. what is its approximate volume? use 3.14 for π. a. 129,400 ft3 b. 79,830 ft3 c. 236,560 ft3 d. 32,366 ft3

V=pi *r^2* h
diameter d= 2r=203
r=203/2=101.50
h=4
V=3.14 * 4 * (101.50)^2
V=129,400 ft^3

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
