# HOW DOES tripling the radius affect the surface area of a cylinder? ### HOW DOES tripling the radius affect the surface area of a cylinder?

Answer: So tripling the radius triples the lateral surface area involves the square of the radius. (b) tripling the radius multiplies the lateral surface area by 3, because the formula for the lateral surface area, , only involves the radius to the first power.

### What happens when you triple the radius of a cylinder?

Answer: It will become nine times of the original volume. Therefore, the volume will be multiplied by nine.

### What happens to the surface area of a sphere if the radius is tripled the surface area is multiplied by?

- Therefore, if you multiply the radius by 3, or triple the radius, the surface area increase by a factor of 9 (3^2=9).

### How do u calculate the surface area of a cylinder?

### How many times larger is the volume of a cylinder if the radius is doubled?

Correct answer: When the radius doubles (r becomes 2r) you get π(2r)2h = 4πr2h. So when the radius doubles, the volume quadruples, giving a new volume of 80.

### Which cylinder has the greatest volume?

Cylinder 1 has the greatest volume.

### How many times does the surface area of a cylinder increase?

The surface area will become 4 times ie increase by 3 times if both radius and height of the cylinder are doubled. The surface area will become 3 times ie increase by 2 times if radius and height are equal and only radius is doubled. The surface area will become ie increase to 2 (1+r/ (r+h)) times if radius is doubled and height remains unchanged.

### What happens to surface area when radius is doubled?

The surface area will become ie increase to 2 (1+r/ (r+h)) times if radius is doubled and height remains unchanged. If the height of a cone is doubled and the radius is halved, what changes are in the volume of the cone?

### How to calculate the surface integral of a cylinder?

Rescale the normal to unit size and you get: If you draw the vertical cross section (the figure on the right), you can see a right triangle that relates the radius of the cylinder with the hypotenuse (the semiaxis): Thanks for contributing an answer to Mathematics Stack Exchange!

### How to calculate the semiaxis of a cylinder with a plane?

The intersection of a cylinder with a plane is an ellipse. Find the semiaxes of the ellipse and you get S = πab The minor semiaxis is always the same as the radius of the cylinder, in this case b = r = 2. The major semiaxis can be calculated from the angle between the plane and the cylinder axis.
