+206 Mrs. Read can knit one pair of children's mittens with a ball of yarn six inches in diameter. How many pairs of identical mittens can she knit with a ball of yarn twelve inches in diameter? Assume that the balls of yarn are rolled consistently.
+37157 VOLUME of 6 inch yarn = 4/3 pi r3 = 4/3 pi 33 ( notte tha r = 1/2 d = 3
12 = 4/3 pi 6^3
3^3 = 27
6^3 = 216 the 12 inch ball is 216/27 = EIGHT times bigger so you would expect she could knit 8 times the mittens
One pair x 8 = 8 pair of mittens
