Answer:
75
Step-by-step explanation:
Flour : sugar = (1/3) : (1/5) = 5 : 3 . . . . . . . . multiply the first ratio by 15 to eliminate fractions
The total of ratio units in the last representation is 5+3=8, so for a recipe of 16 cups, each ratio unit will stand for 16/8 = 2 cups.
Multiplying the ratio by 2 cups, we find Amanda will need
... 10 cups flour : 6 cups sugar
for her recipe.
The volume formula for a sphere is 4/3 Pi R^3 (Radius cubed).
6.5 x 6.5 x 6.5 = 274.625
274.625 x 3.14 = 862.3225
862.3225 x (4/3) = 1149.763
I hope this helps!
