Is it true or false that a radius is a chord of a circle?
False
If you know the diameter of a sphere you can find its radius true or false?
True. The radius is half the diameter.
One radius of a circle is the same length as any other radius of the same circle?
true (apex
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.
All circle are also ellipse true or false?
true
Is it true or false that a radius is a chord of a circle?
False
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.
True or False If a radius of a circle intersects a chord then it bisects that chord?
False
True or False If a radius of a circle intersects a chord it is perpendicular to that chord?
its false
Is the distance from the point of concurrency of the angle bisectors of a triangle to a point on the inscribed circle is the radius of the circle True or False?
false
An angle whose vertex is at the center of a circle is a middle angle of that circle True or false?
False. There are infinitely many angles at the centre of the circle.
The shortest distance from the center of the circumscribed circle to the vertices of the inscribed triangle is the circles radius?
False apex q
True or False if a radius of a circle is perpendicular to a chord then it bisects that chord?
true, because both distances of the chord are congruent
The distance from the point of concurrency to the side of the circle is the radius of the circle is this statement true or false?
Neither. The statement does not specify the point of concurrency of WHAT!
To find the area of a circle multiply 2 times 3.14 by the radius is this true or false?
False. If you do this you will find the circumference (2 x radius x pi). Area = 3.14 times (radius squared)
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.
Which is true about the radius of a circle?
That it is half the diameter of a circle
