That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

If the circumference of a circle doubles the radius?

IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius


What does 2 pi r or 2 pi radius mean?

2 x Pi x r is equal to the circumference of a circle whose radius is equal to r.


Is circumference radius times pi?

No it is 2*radius*pi or diameter*pi or 2(pi)r


How do you work out the area if given the circumference?

Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)

How do you convert basic circumference into radius?

Circumference = 2*pi*radius Radius = Circumference/(2*pi)


How do you find the diametre if you have the area?

Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)


When given circumference how do you find the radius?

Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)


Formulas with include pi?

Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Volume of a sphere: 4/3*pi*radius^3 Surface area of a sphere: 4*pi*radius^2


How do you find the radius with only the circumference?

Circumference = 2*pi*radius So Radius = Circumference/(2*pi)


3 mathematical formulas including pi?

Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Surface area of a sphere: 4*pi*radius^2


What is 2 pi radius?

Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter diameter x pi = circumference (distance around) 2 pi radius is the circumference of a circle


What is the radius of a circle with a circumference of 8 centimeters?

Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)


What is th radius and diameter of a circle with a circumference of 90 inches?

Circumference = 2*pi*radius or circumference/2*pi = radius 90 inches/2*pi = 14 inches in radius =======================


How do you find the diameter of a circle if they give you the area?

Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)


How do you find the area if you have the circumference?

If you mean a circle, first find out the radius (circumference = 2 x pi x radius, so you divide the circumference by 2 and by pi).


Is circumfrience pi times radius to the 2?

circumfrience is pi times radius to the 2 i think


Why is diameter pi and 2 pi radius equivalent?

because, diameter = 2 x radius

Circumference = 2 * Pi * radius Radius = 23 / (2 * Pi) Radius = 3.66 inches


How to relate the ratios of circumference and radius with pi?

C = 2*radius*pi


How do you find circumference when you have the radius?

multiply the radius by 2, then by pi, where pi is about 3.1416
