How do you increase the size of a circle?
Increase the length of the radius
If the radius of a circle is increased by 20 percent then the area is increased by?
Area = pi r2 A = pi(r+20%)2 ----->INCREASED AREA A = pi(r+0.2) 2 A = pi(r2+0.4r+0.04) = pir2 + 0.4pir+ 0.04pi But the Area of the circle is pir2, so subtract the original area from the increased area! pir2+0.4pir+ 0.04pi - pir2 0.4pir + 0.04pi-----------ANSWER % ORpi(0.4r+0.04) pi = 3.142 but we do not know the value of radius. If is a unit circle we can give acurate %
ByWhat percentage is the cross sectional area of a circle increased if the radius is doubled?
300. (Doubling the radius multiplies the area by four times.)
When the radius of a circle is tripled what happens to the area?
It is increased nine fold. New Area = 9*old area.
Which term describe the distance from the center of a circle to any point on the circle?
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

If a radius of a circle is increased by 10 percent by what percent does its area increase?
area goes as radius squared 1.1 x 1.1 = 1.21 or 21%
What happens to the circumference of a circle when the radius is increased by 50 percent?
The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.
What happens to the area of a circle of its radius is increased by100 percent?
The area is increased by 300%.
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 take a circle and enlarge it by 150 percent?
Increase the radius sqrt(1.5) = 1.2247 times.
What percentage of diameter of a circle is the radius?
50 percent of diameter of a circle is the radius.
How do you increase or decrease the radius of a circle?
Increase or decrease the circle's diameter
How do you increase the size of a circle?
Increase the length of the radius
If the circumference of a circle is increased by 50 then the area will be increased by?
there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.
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 is the radius if the size factor is fifty percent of a circle?
radius is 2
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.
