The diametre of a circle is a line which joins two points on the circle and also passes thriugh the centre of the circle. Express the diametreof the circle(d) in terms of its radius(r). "It is of algebra"
Answers
Answer:
d_2r
Step-by-step explanation:
diameter of a circle is twice its radius,where radius is alone joining centre to a point on the circle .
For Expressing the diameter of the circle(d) in terms of its radius(r) , we have to know that what is diameter and what is radius .
DIAMETER : A diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle.
RADIUS : A radius of a circle is any of the line segments from its centre to its perimeter.
Connection between diameter and radius of a circle:
Diameter is a line that passes through the centre of circle and radius is a line that passes from the centre of circle .
So , the length of diameter is equal to twice the length of a radius or,
d =2 * r
hence, d = 2r
