Answer:
Yolanda should have found the volume by multiplying 8 by four-thirds
Step-by-step explanation:
Here, we want to find Yolanda’s error.
we proceed as follows;
Mathematically, the volume of the cylinder can be calculated using the formula;
V = pi * r^2 * h
now since the radius of the cylinder and the height is equal, we can say that h = r
and thus, the volume can be written as
V = pi * r^2 * r = pi * r^3
Mathematically, the volume of a sphere can be calculated using the formula
V = 4/3 * pi * r^3
Now from the question we know that the value of pi * r^3 =8 which is the value for the volume of the cylinder.
Thus the volume of the sphere would be 4/3 * 8
so the correct answer here is B
