radius = diameter/2
radius = diameter/2.
The formula is 2pie(radius).
radius x radius = # pi X # = answer... pi x radius, square the radius
It is: 2*pi*radius
Well to find the radius it is diameter/2.
Radius, "R" = D/2 where D=Diameter.
A radius is a line segment. It has no area.
Diameter divided by 2 = radius
radius = 1/2 diameter
3.14 times the radius times 2
Diameter = 2*Radius
Half the diameter
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
The answer depends on the radius of what! The formula for a circle or sphere are different. The answer also depends on what information is available about the circle or sphere.
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
Well the formula for the radius of the square is radius squared * pi (3.14)So find the radius (which is half of the diameter. which is exactly half of the shape)and do the formula. end the answer with "m".
The radius is 1.5. The formula to get the radius is Diameter/2.
what is the radius? It depends on the the radius. Formula 3.14*radius squared*5=answer
Hell are you talking about?!? A radius is a dimension of a circle! A rectangle has no stinking radius!
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
== A radius is half of diameter,the formula of radius== d/2 ===
Circumference = 2*pi*radius
A radius is a 1-dimensional object and so it has no volume.
