What do you call line segment in a circle?
A. If the line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. B. If the line segment touches one point on the circle AND the center of the circle AND is present only within the circle it is called as: radius.
What is an area of a circle bounded by two radii?
Working in degrees, the angle of the greater radius, minus the lesser radius, all over 360, gives the proportion of the area of the circle that is bounded by the radii. This can then be multiplied by the area of the whole circle to give the bounded area.
What does the radius of a sphere?
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
How many points are represented In a quadrilateral?
Infinitely many points are contained within a non-degenerate quadrilateral.
What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm?
The probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius). Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
What is the difference between a circle to an oval?
circle has single center point and is equidistant to point of radius,while oval has four(4) center points with two(2) different radius.
A radius is a chord of a circle?
No. A chord is a straight line within a circle that meets the circumference at two points and divides the circle into two arcs. A radius is a straight line from the centre of the circle to the circumference and is therefore not a chord. However, a diameter is a chord passing through the centre of the circle.
What is are the points in a a circle?
The points in a circle are just points in a circle. Also, a plane cannot be within a circle because planes go on forever in all directions, so a circle can be within a plane.
How do you work cicumferencediameterradiusarea of a circle?
The circumference of a circle is the distance around the circle. The formula is: C = pi * d (where pi = 3,1416 and d is the diameter) The diameter of a circle is the distance across the circle. The radius of a circle is one-half of the diameter The area of the circle is the amount of space contained within the circle. To calculate, the formula is: A = pi * r-squared (where pi = 3.1416 and r-squared is the radius multiplied by itself)
What do you call line segment in a circle?
A. If the line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. B. If the line segment touches one point on the circle AND the center of the circle AND is present only within the circle it is called as: radius.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
What is an area of a circle bounded by two radii?
Working in degrees, the angle of the greater radius, minus the lesser radius, all over 360, gives the proportion of the area of the circle that is bounded by the radii. This can then be multiplied by the area of the whole circle to give the bounded area.
State a definition for a polygon inscribed in a sphere?
Inscribed polygon: a polygon contained within a circle, with each side being a chord of a circle.Chord: end points connected to an arc or a semicircle, forming a segment that lies in the interior of a circle.
What does the radius of a sphere?
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
How many points are represented In a quadrilateral?
Infinitely many points are contained within a non-degenerate quadrilateral.
A large circle has a radius of 10cm Given four congruent circles tangent to one another within the large circle what is the radius of the largest circle which will fit in the middle?
Letting x be radius of the 4 circles, then (squareroot(2x^2))+x=10, or x(1+sqrt2)=10. Then radius of circle in middle is ((2*10)-4x)/2. So I get radius of circle in middle = 1.715729 approximately.
What is the perimeterand area of a circle?
Ok,To find the Perimeter of a circle, you must use the formula;P = 2 * (PI) * rwhere P = PerimeterPI is the constant (approx. 3.14159)& r is the radius of the circle.As the diameter of the circle is double the radius, you can also say;P = d * (PI)Note: * means 'multiplied'.(Perimeter, is the distance around the outside of a circle.)To find area of a circle, you need to use the equation;A = (PI) * r^2A = Area^ = to the power of.i.e The area of the circle equals the radius squared times the constant PI. (Area, is what is contained within the circles perimeter.)Hope this helped!jdru4706
