What happens to a circle when the radius is doubled?
The area quadruples.
What happens to its cross-sectional area of the metal wire if you double the radius?
It quadruples.
What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
If the radius of a sphere is doubled what is going to happen to the surface area?
the surface area quadruples.
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.
When the radius of a circle is doubled what happens to the area?
It quadruples.
What happens to a circle when the radius is doubled?
The area quadruples.
If the radius of a circle is doubled what happens to the area?
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).
What happens to its cross-sectional area of the metal wire if you double the radius?
It quadruples.
If the radius of a circle is doubled what happens to the area of the circle?
the area of the circle is increased by 400%
What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
What happens to the area of a circle if the radius is tripled?
The circle becomes an oval
What happens to the area of a circle whose radius is halved?
the area of the circle will be 1/4 of its original area
If the radius of a sphere is doubled what is going to happen to the surface area?
the surface area quadruples.
What happens to the area of a circle if you triple a radius?
When you triple the radius of the circle . . . -- The diameter also triples. -- The circumference also triples. -- The area is multiplied by 9 .
What happens to the area of a circle when the radius is triple?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
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.
