To increase the area of a circle you must increase the radius.

Decrease The Length of The Radius

Decrease

Increase the length of the radius

By reducing its radius or diameter.

it will decrease as radius increase keeping mass same

If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.

The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.

Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.

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.

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

increases

Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.

An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.

Increase in the core temperature and decrease in the core radius.

the radius of a circle is r

The radius of a circle is half the circle's diameter

The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.

It will decrease not by much though it is not noticeable compared to the earths radius

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.

in general it decreases

The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938

no.the radius of a circle is the distance from the middle of the circle to the edges. no.the radius of a circle is the distance from the middle of the circle to the edges.

radius of any circle = diameter/2

If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.
