To convert a mixed fraction into an improper fraction:
That is going to be 48 for the first question because 6x8 equals 48
Step-by-step explanation:
Let's say R is the initial radius of the sphere, and r is the radius at time t.
The volume of the sphere at time t is:
V = 4/3 π r³
Taking derivative with respect to radius:
dV/dr = 4π r²
This is a maximum when r is a maximum, which is when r = R.
(dV/dr)max = 4π R²
This is 4 times the sphere's initial great circle area, but not the great circle circumference. The problem statement contains an error.
So you cant have a decimal in your divisor which means the problem sill become 18215/7 if that helps
