Area is proportional to the square of the linear dimensions.
If diameter is tripled, area increases by a factor of (3)2 = 9 .

What is the perimeter of 21 mi of a circle?
The perimeter of a cirlcle is its circumference which is: 2*pi*radius or diameter*pi
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
When the radius of a circle is tripled what happens to the area?
It is increased nine fold. New Area = 9*old area.
What happens to the diameter if the circumference is doubled?
The diameter of a circle is doubled if the circumference is doubled.
If the circumference of a circle is doubled what happens to the diameter?
If you double the circumference. the diameter like wise would double.
What happens to the circumference of a circle if its diameter is tripled in size?
9 times bigger
What happens to the circumference when the diameter of a circle is doubled or triple?
The circumference is doubled or tripled, respectively.
If the diameter of a circle 20 cm is tripled what will the area be?
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
How do you work out the circumference of a cirlcle?
Given the diameter of the circle, multiply it by π (approx 3.14159).
What is the perimeter of 21 mi of a circle?
The perimeter of a cirlcle is its circumference which is: 2*pi*radius or diameter*pi
What happens to the area of a circle if the radius is tripled?
The circle becomes an oval
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
Is diameter the measurement across a circle or the measurement around a cirlcle?
"Diameter" is the distance all the way across the circle, through the center."Radius" is 1/2 of the diameter ... the distance from the center to the curvy part of the circle."Circumference" is the distance all the way aroundthe circle.
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.
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
How does the circumference of a circle change when its diameter is tripled?
C1 = pi x D, C2 = pi x 3 x D, so the circumference is also tripled.
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.
