no
How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x 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.
The area of a circle of radius 10 units is equal to the surface area of a sphere of radius 5 units?
true
How do you get the radius from the circumference?
The circumferance of a circle is equal to 2 x pi x r, where r is the radius, i.e. approximately 6.2832 than its radius. Divide the circumferance from the figure above to get the radius of a circle in which the circumferance is known.
The line which is at a distance equal to the radius of a circle from its centre is called?

What is the formula for radius of sphere?
The radius of a sphere is equal to one-half the diameter. If the volume of the sphere is known, then the radius (r) is equal to the cube root of 3/4 of (Volume/pi).
Is H's atomic radius equal to He atomic Radius?

Can the focal length of a lens be equal to its radius?
Radius of cuvature = 2 x focal length So both cannot be equal in any way
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
