If the radius of a circle is doubled the how does that effect the area?
The area of the circle will be 4 times greater
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).
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.)
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
What happens to the area of a circle if the circumference is doubled?
Oh, dude, if you double the circumference of a circle, the area will also double. It's like they're best friends or something. So, if you're out there stretching circles, just know that their area will stretch along with them.
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%
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.
What happens to the area of a circle when the radius is doubled tripled?
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 the circle when the diameter is doubled?
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
If the radius of a circle is doubled the how does that effect the area?
The area of the circle will be 4 times greater
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
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 the area of a circle when its doubled?
When the diameter is doubled, perhaps? Then the area is 4 x larger.
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.)
What happens to the area of a circle when the diameter is doubled?
the area is increased by 4 times
What happens to the area of a circle if the diameter is doubled?
If you double the diameter of a circle, the area will quadruple (be 4x greater).The area of the circle increases exponentially with the diameter, or more precisely with the radius, which is 1/2 the diameter. A = (pi)r2Doubling the diameter of a circle will quadruple the area (22 =4).This is easily seen in pizzas, where the dough needed for a 16-inch pizza can be used instead to make 4 pizzas with a diameter of 8 inches.---The equation to find the area of a circle is a=(pi)r2. If the diameter is doubled, then the radius is also doubled, because the radius is just half the diameter.The area of a circle once its radius (and therefore diameter) has been doubled can be expressed as follows: a'=(pi)(2r)2, which simplifies to a'=(pi)(4r2).To find the proportion of a' and a, we just divide the second by the first. This gets us[(pi)(4r2)]/[(pi)(r2)]=4
