Question 1018110
Radius is 1/2 diameter. In this problem:
2.1*1/2 = 2.1/2 = 1.05 is the radius
Weight:
{{{volume*density}}}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Volume of the sphere:
{{{V = (4*pi*r^2)/3}}}
{{{V = (4*3.1416*1.05^2)/3}}}
{{{V = 4.62}}}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Weight:
{{{11.34*4.62 = 52.39}}} is the weight of this ball.
