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.
Can you develop a formula for the area of a circle as a function of its circumference?
It's pretty straightforward. The circumference of a circle is given by the equation C = 2[Pi]r, which can be rewritten as r = C/2Pi. The area of a circle is given by the equation A = [Pi]r2. Substituting for r in that equation gives us A = Pi(C/2Pi)2 = [Pi]C2/4[Pi]2 = C2/4Pi So, A = C2/4Pi. You can see that the area of a circle is proportional to the square of its circumference, so if you double the circumference, you quadruple the area. If you triple the circumference, the area increases ninefold! If you like, you can remember the formula as A = kC2, where k = 1/4Pi = 0.0796
How do you triple the lateral surface area of a cone?
Assuming you want to make a figure that is bigger, but similar (all measurements proportional): for any simular figures, surface area is proportional to the square of any linear measurement, so you would have to increase both the diameter and the height by a factor square root of 3
What is the first triple digit pentagonal pyramidal number?
first triple digit pentagonal pyramidal number is 126
Would tripling the height of a triangular prism triple its volume?
If you triplied the height of a triangular prism, would that triple it volume
What happens to the circumference when the diameter of a circle is doubled or triple?
The circumference is doubled or tripled, respectively.
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 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 .
How does the circumference of a circle change if you triple its diameter?
three times
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.
How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
What happens if you triple the radius of a circle?
If you triple the radius of a circle . . . -- You should not expect anything to happen. Those around are likely to remain completely unaware that you have done anything to your circle. -- You wind up with a circle that's three times as big as it used to be. -- The diameter of the circle is three times the original diameter. -- The circumference of the circle is three times the original circumference. -- The area of the circle is nine 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 is the approximate circumference?
Triple the diameter is.
What happens if you triple the radius?
in what? a circle?
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.
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.
