Practice Circles MCQs from Geometry — Mathematics.
A chord AB of a circle divides it into two segments. If the angle in the minor segment is 120 degrees, what is the angle in the major segment?
In a circle with center O, the measure of central angle AOB is 80 degrees. If the area of sector AOB is 16*pi, what is the radius?
The angle between a tangent and its radius is always constant. What is that constant?
What is the relationship between the radius (r) and the diameter (d) of a circle?
If the radius of a circle is 7 cm, what is its circumference? (Take pi = 22/7)
What is the area of a circle with a diameter of 14 cm? (Take pi = 22/7)
What is the degree measure of an angle inscribed in a semi-circle?
If two circles have the same center but different radii, they are called:
What is the sum of opposite angles in a cyclic quadrilateral?
A line segment joining any two points on the circumference of a circle is called:
If the circumference of a circle is 132 cm, find its radius. (Take pi = 22/7)
How many tangents can be drawn to a circle from a single point outside the circle?
The angle subtended by an arc at the center of a circle is 80 degrees. What is the angle subtended by the same arc at any point on the remaining part of the circle?
What is the length of the longest chord of a circle with radius 5.5 cm?
If an arc subtends an angle of 60 degrees at the center of a circle of radius 21 cm, find the length of the arc.
A circle is divided into two parts by a chord. The larger part is called:
