Question

A spherical snowball is melting. The radius after t hours is 1-t meters. [Volume of a sphere of radius R is 4R3π/3] (a) What fraction of the initial mass of the snowball remains after half an hour?

Answer 1

Answer:

$0,52m^{3}$

Step-by-step explanation:

r=(1-tm)   $Vs=\frac{4\pi r^{3} }{3} =\frac{4\pi (1-t)^{3}}{3}=4,18(0,5)^{3} = 0,52m^{3}$
