What else can I help you with?
How can you change the radius of the circle to increase the area?
To increase the area of a circle you must increase the radius.
How do you decrease the size of a circle?
Decrease The Length of The Radius
How do you decrease he size of a circle?
By reducing its radius or diameter.
As the diameter of the circle increases what happens to the circumference?
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
If the radius of a circle decreased would the area decrease?
Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.

What happens to the gravitational field strength as you increase the radius?
it will decrease as radius increase keeping mass same
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
What happens to the surface temperature of a planet if you decrease its orbital radius?
If you decrease a planet's orbital radius, its surface temperature will increase.

What factors affect the increase of the centripetal force on a particle in uniform circular motion?
Increase in radius affect the increase of the centripetal force on a particle in uniform circular motion. An increase in radius would cause a decrease in the force if velocity remains constant.
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 you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
