Perimeter is proportional to the linear dimensions, so it increases by 3x .
Area is proportional to (linear dimensions)2, so it increases by 9x .

When the diameter of a circle is tripled what happens to the area of the cirlcle?
Area is proportional to the square of the linear dimensions.If diameter is tripled, area increases by a factor of (3)2 = 9 .
If two polygons are similar how can you find the scale factor from one polygon to the other?
divide the perimeter by 27 the multiply it by 3 and then u get the answer
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
If the side of a square is doubled in size to 8 by what percent did its area increase?
If the side of a square doubles, its area increases by a factor of 4 - an increase of 300%.If the side of a square doubles, its area increases by a factor of 4 - an increase of 300%.If the side of a square doubles, its area increases by a factor of 4 - an increase of 300%.If the side of a square doubles, its area increases by a factor of 4 - an increase of 300%.
Two similar triangles have a scale factor of 14 If the perimeter of the smaller triangle is 10 what is the perimeter of the larger?
the answer to this question is 1:4 10: ? =10x4/1 =40
When displacement per unit time is tripled the velocity increases by what factor?
three times
When the diameter of a circle is tripled what happens to the area of the cirlcle?
Area is proportional to the square of the linear dimensions.If diameter is tripled, area increases by a factor of (3)2 = 9 .
If a rectangular dimensions ge multiplied by 4 what does the perimeter get multiplied by?
The perimeter correspondingly increases by a factor of 4.
What is the relationship between scale factor and perimeter?
It is a strict linear relationship. Double the size, double the perimeter. The area, however, increases by the square of the scale factor.
What happens if a circle's radius is tripled?
If the radius is tripled then the Area will be greater by a factor of 9. And the circumference will be greater by a factor of 3.
If two polygons are similar how can you find the scale factor from one polygon to the other?

How does the perimeter of a figure change if the dimensions are changed from yards o feet?
The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.
When all dimensions are tripled what happens to the volume?
If linear dimensions are increased by a certain factor, the volume will increase by that same factor, raised to the third power - so, in this case, 3 to the power 3.
How does scale factor relate to perimeter?
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
Two similar rectangles have sides in ratio to two thirds what is the ratio of the perimeters?
Theorem: If two similar triangles have a scalar factor a : b, then the ratio of their perimeters is a : bBy the theorem, the ratio of the perimeters of the similar triangles is 2 : 3.For rectangles, perimeter is 2*(L1 + W1). If the second rectangle's sides are scaled by a factor S, then its perimeter is 2*(S*L1 + S*W1) = S*2*(L1 + W1), or the perimeter of the first, multiplied by the same factor S.In general, if an N-sided polygon has sides {x1, x2, x3....,xN}, then its perimeter is x1 + x2 + x3 + ... + xN. If the second similar polygon (with each side (labeled y, with corresponding subscripts) scaled by S, so that y1 = S*x1, etc. The perimeter is y1 + y2 + ... + yN = S*x1 + S*x2 + ... + S*xN = S*(x1 + x2 + ... + xN ),which is the factor S, times the perimeter of the first polygon.
What does the scale factor between two similar figures tell you about the perimeter?
The perimeter will scale by the same factor.
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
