Question 828727
surface area of sphere = {{{4(pi)r^2}}}
Assume the baseball has a radius of 1 unit.
The basketball has a radius of 4.1 units.
So the ratio of surface areas is
{{{(4(pi)(4.1)^2)/(4(pi)(1)^2)}}}
{{{(4(pi))}}} cancels out
{{{((4.1)^2)/(1)^2)}}}
{{{16.81/1}}}
So the surface area of the basketball is 16.81 times larger.
