Answer:
B. 8.0 cubic inches
Step-by-step explanation:
You need to find 190% of the volume of a gumball which is a sphere.
To find 190% of a quantity, multiply the quantity by 1.9.
volume of sphere = (4/3)(pi)(r^3)
diameter = d = 2 in.
radius = r = (1/2)d = (1/2)(2 in.) = 1 in.
volume of sphere = (4/3)(3.14159)(1 in.)^3 = 4.189 in.^3
The volume of a gumball is 4.189 in.^3
Now we need 190% of that volume.
190% of volume of sphere = 1.9 * volume = 1.9 * 4.189 in.^3 = 7.959 in.^3
Rounded to the nearest tenth, the volume is
B. 8.0 cubic inches
