In the formula for the area of a circle what gets multiplied by 3.14?
The radius squared. The radius is half of the diameter
What happens to the area of a circle when the diameter is halved?
When the diameter of a circle is halved, the radius is also halved since the radius is half of the diameter. The area of a circle is calculated using the formula A = πr^2, where r is the radius. If the radius is halved, the area is reduced to one-fourth of its original size because the radius is squared in the formula. Therefore, halving the diameter of a circle results in the area being reduced to one-fourth of its original area.

In the formula for the area of a circle what's gets multiplied?
Algebraically, it is ; - A = pi r^(2) In words, it is ' Area equals 'pi' multiplied to the radius squared'. NB 'pi' is a constant at 3.141592..... usually shortened to '3.14'. The radius (r) is the distance from the circle centre to the circumference/edge. 'radius squared' is r^(2) , that is 'r' multiplied to 'r' ; r X r = r^(2) . NNB The circumference of a circle is ; C = 2 pi r Note the power/exponent of '2' becomes a coefficient. In words ' Circumference equals two multiplied to 'pi' multiplied to the radius. (NOT radius squared).
What happens to circumferences and areas when the radius of circle is multiplied by some number x?
The circumference of a circle is 2 * pi * r. If you multiple r by x you get 2 * pi * (r * x) which is the same as x * (2 * pi * r). So the circumference is multiplied by x. The area of a circle is pi * r2. Multiply r by x and you get pi * (rx)2 which is the same is (pi * r2) * x2. So the area gets multiplied by x2.
How do you find the circumference when you have area?
if your talking about a circle, then: Area = pi*radius^2, so you can use the area to find the radius, and then all you need to do is use the formula Circumference = 2*pi*r If its a different shape it gets slightly more tricky

When was Circle Gets the Square created?

How would you find an oval with the same area of a circle?
An oval is a general word that could have different shapes. If you squash a circle evenly, the new shape in math is called an ellipse, which has an oval shape. The formula for the area of a circle is Pi times the Radius of the circle squared. The radius is half the height of the circle and also half the width of the circle. The general formula for the area of an ellipse is Pi times half the height times half the width. So we say length A is half the height of an ellipse and length B is half the width of an ellipse. When A is equal to B you have a circle. When they are different you have an ellipse. So if you want the area of the circle to be the same as the area of the ellipse, then you have to keep the height times the width the same for the ellipse as it was for the circle. As you squash the ellipse further the width must stretch out more than the height gets pushed down. For example, a circle with radius of 1 inch would have the same area as an ellipse with height ½ inch and width 2 inches because 1 times 1 is equal to ½ times 2. Another ellipse with the same area could have height ¼ inch and width 4 inches.
