R+14=39
r + 14 = 39 r = 25
39-14=25 so R=25 25+14=39

In the equation g = rz, r represents a variable or a constant value. The specific value of r would need to be provided in order to determine its numerical value in the equation.
It is an equation and the value of r is 66
Without an equality sign the given expression can't be considered to be an equation.
For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
y=a(1-r)^t where a is the initial value, r is the rate as a decimal and t is the time in years.
