Tripling the radius of a sphere increase the surface area by a factor?

By a factor of 32 = 9. In general, surface area (for any two similar objects) is proportional to the square of any linear measurement.

What happens to the area of a circle when you triple the radius?

As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.


As the radius of a sphere gets larger which of the spheres measurements increases more the surface area or the volume?

The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)


What happens to the surface area of a sphere if its radius is doubled?

If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.


What happens to the cylinder's surface area if its radius is squared?

It remains the same or increases in surface area.


If the radius of a sphere is tripled what is going to happen to surface area?

If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.


What effect does tripling the radius and doubling the height of a cone have on the cone's volume?

the volume changes as radius squared and linear with height, so tripling radius and double of height gives 3 x 3 x 2 = 18 times more volume


If you double the radius of cylinder how does this affect the volume of the cylinder?

The volume increases by a factor of four.


How would an increase in mass affect the basic properties of a star?

As mass increases It increases the surface temperature , luminosity, and radius.
