What happens to the circumference of a circle if you triple the radius?
Since circumference is proportional to the diameter (the proportionality is the definition of the irrational number pi) and the radius is just twice the diameter, if you triple the radius, you also triple the circumference.
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
What happens if you triple the radius in a circle?
nothing you will just just get the radius in 3 circles.
Why the area is multiplied by 9 if you triple a radius?
Because the area of a circle is pi*radius2. So, if you triple the radius to 3*radius, the area becomes pi*(3*radius)2 = pi*(32*radius2) = pi*9*radius2 that is, 9 times the original area.
If you triple the radius of a circle how is its circumference affected?
The circumference of a circle = 2*pi*r. if you triple r, the circumference is tripled also.
What happens to the circumference of a circle if you triple the radius?
Since circumference is proportional to the diameter (the proportionality is the definition of the irrational number pi) and the radius is just twice the diameter, if you triple the radius, you also triple the circumference.
What happens if you triple the radius?
in what? a circle?
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
What happens to the area of a circle if you triple a radius?
When you triple the radius of the circle . . . -- The diameter also triples. -- The circumference also triples. -- The area is multiplied by 9 .
What happens if you triple the radius in a circle?
nothing you will just just get the radius in 3 circles.
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
Why the area is multiplied by 9 if you triple a radius?
Because the area of a circle is pi*radius2. So, if you triple the radius to 3*radius, the area becomes pi*(3*radius)2 = pi*(32*radius2) = pi*9*radius2 that is, 9 times the original area.
What happens to the area of a circle when the radius is triple?
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.
If you triple the radius of a circle how is its circumference affected?
The circumference of a circle = 2*pi*r. if you triple r, the circumference is tripled also.
If you triple the radius of a circle what happens to the area?
The result is 9 time the original.
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 perimeter and area of the circle?
The perimeter would triple and the area would be multiplied by nine (32). Circumference (perimeter) is (2 x pi x r), so would be (6 x pi x r) for triple the radius, and area is (pi x r2), so would be (pi x 32 x r2) for triple the radius.
