The formula for the area of a circle is, A = πr2
If the area is tripled then the larger circle has an area of A2 = πR2 (where R is the new radius)
But, πR2 = 3πr2 : R2 = 3r2 : R = r√3
The circumference of the original circle was 2πr.
The circumference of the larger circle is 2πR = 2πr√3
Therefore, if the area is tripled, then the circumference increases by √3.
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.
You dived the area by the circumference of the circle.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
The area of a circle with circumference 9.42in is: about 7.061 square inches.
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.
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 .
Circumference(C) = 2πr C is directly proportional to r. If radius is tripled then circumference becomes three times of the initial. Since the radius is tripled so the new radius is 3r. New circumference(C') = 2π(3r) = 3 x (2πr) = 3 x C Area = πr2 A is directly proportional to r2. If radius is tripled then area becomes 9{square of 3} times of the initial. New radius is 3r. New Area(A') = π (3r)2 = 9 x π r2 = 9 x A.
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
The circle becomes an oval
You dived the area by the circumference of the circle.
Because the perimeter (circumference) is 2*pi*r is proportional to r. The area a = pi * r2 is proportional to r2
No,Circumference is like the perimiter and Area is the whole circle.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The area of a circle that has a circumference of 16pi is: 201.1 units2
