What is the diameter of a cup?
The diameter of a circle is the length of a straight line segment going from one point on the circle to a point on the opposite side, passing through the center point of the circle. The diameter of a cup would be the diameter of the circular face of the cup.
What is surface area of pencil with 15cm and 0.6cm in diameter?
Ignoring the point and assuming a cylindrical pencil then the surface area would be made up of one rectangle and two circles. The circles would have areas of 3.14 x 0.32 = 0.28cm2 giving a total for both ends of 0.56cm2 The rectangle would have a length of 15cm and a height of 3.14 x 0.6 = 1.88 thus having a total area of 28.26cm2 Thus the total area would be 28.26 + 0.56 = 28.82cm2 If you sharpen the pencil then the calculation becomes more complicated and you'd have the know the angle of the sharpened end
What do you call a circle with a dot in the middle in radius and diameter?
The distance from a circle to its center (the dot in the middle) is called 'the radius'. The distance from a circle to a point opposite is called 'the diameter'. The diameter is twice the length of the radius.
What is the length of the diameter of a circle if the radius is 3.2 cm?
6.4cm since the radius of a circle is it's center point to any place on the side. A diameter is the straight line that comes from one point on the side passes through the center point and touches the other side Bottom Line: The diameter is double the radius.

Which best explains why points cannot have a diameter of 0.01 in?
A mathematical point is only a location, and has no dimensions. Of course, when you mark the point on paper, it has the same diameter as the lead in your pencil, or the ball on your BIC.
What makes a pencil write?
The pencil doe not write. It is the person that picks up the pencil that writes with the pencil. when the point of the pencil is put to a surface ( IE. a sheet of paper) to be written on the graphite tip being soft is worn down leaving a line on the surface of the paper.

The diameter of a circle is the length of a straight line segment going from one point on the circle to a point on the opposite side, passing through the center point of the circle. The diameter of a cup would be the diameter of the circular face of the cup.
What is the difference of diameter and meter?
The diameter is a straight line going from a point on the circumference of a circle, through the centre of the circle, to another point on the circumference. It can be of any length. A metre is a standard unit for measuring length.

How can you use a compass to draw a circle if you know its raduis or diameter?
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.

Diameter of a circle is 16cm what is the radius?
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
What is the relationship between the radius and the diameter?
The radius of a circle is half the length of the diameter. Scroll down to related links to find more about the diameter and the radius.
What is the radius of a circle with a diameter of 144?
72 The diameter is the full length from left to right and the radius is taken from a central point, in this cas at the 72 mark.
