starting size n, surface area = 6 x n2; starting size 2n surface area 6 x 4n2 so surface area would be quadrupled.
The area of the circle will be 4 times greater
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.
The area will be four times larger because both the length and the width of the original shape were doubled in size. Thus, each dimension was multiplied by a factor of two, resulting in an overall increase of four.
The area increases, but there's no way to say by how much in general. The percent increase is different in different cases.
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
Surface Area becomes 4 times the original when its edges are doubled because Suraface area = (edge)^2
The area increase by four times.
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
It will increase to four times as much.
It will increase by a factor of 4; in other words, it will be 4 times greater. Given that all sides of a cube are of equal dimension, I will call this variable dimension x. The surface area is, therefore, x2. If the side of the cube is doubled (2x), then the surface area would be (2x)(2x) = (2x)2 = 4x2. So: x --> 2x (the side length is doubled) x2 --> 4x2 (the surface area is quadrupled)
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
The surface area goes as the edge ength squared, so if you double the edges you get four times the area
The area would become four times larger. The area increase is always the perimeter increase, squared. For example. If the sides of a square were quadrupled, the area would become sixteen times larger.
If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.
the surface area quadruples.
The surface area is quadrupled.
The new area is 22 = 4 times the original area. The new volume is 23 = 8 times the original volume.
