If you know the diameter of a sphere you can find its radius true or false?
True. The radius is half the diameter.
Is the area of a circle twice the radius True or false?
True
The diameter of a circle is always twice the length of the radius?
True !! it is also a straight line from one side of the circle, through the middle point to the other side of the circle. Any other straight line inside a circle, that does NOT touch the centre is a chord.
What is the circumference of a circle if a circle has a radius of 226.08 dm and a diameter of 36dm?
The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
Is it true that circles with a radius of Cm have circumferences of the same length?
Yes, it is true. Any circles with the same radius will have the same circumference as well.
Why is the diameter of a circle always twice the length of the radius?
A circle is the locus of points that are equidistant from a fixed point. As a result, all radii of the circle must be of the same length. A diameter is a straight line that goes from the circumference to the centre and on to the circumference on the other side. Thus it is a radius from the circumference to the centre and then another radius from the centre to the circumference. And since these are the same, it is 2 radii in length.
If you know the diameter of a sphere you can find its radius true or false?
True. The radius is half the diameter.
What is the radius if the diameter is d equals 16inches?
A true and useful definition of "radius" is that it's 1/2 of the diameter.
What is the radius of a circle in millimeters?
It varies on how large the diameter and radius is. True, but with the radius you know to double it and you have the diameter. If you muliply Pi (3.14....) times the diameter, you get the circumference. So radius = circumference divided by Pi, with that answer (which is "diameter")then divided by two.
Is the area of a circle twice the radius True or false?
True
Which is true about the radius of a circle?
That it is half the diameter of a circle
Is it true or not true that radius circumference and diameter was named after a king queen or prince?
It is not true
The diameter of a circle is always twice the length of the radius?
True !! it is also a straight line from one side of the circle, through the middle point to the other side of the circle. Any other straight line inside a circle, that does NOT touch the centre is a chord.

The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
How do you find true length of a sphere?
The length of a sphere is its diameter
Is this statement true or falseThe side length of a regular hexagon is equal to the length of the radius?
true
True or false the radius r of circle is the distance across the circle through its center?
False:: The distance from the circle centre to the circulference is the RADIUS. However, As a straight line, the distance from the circumference , through the circle centre to to circumference on the opposite side is the Diameter. The diameter is twice the radii. Algebraically, d = 2r.
