The center circle is 10 yards in radius. The penalty arc is 10 yards from the penalty mark. The corner arcs are all 1 yard from their corresponding corner. A semi-circle is exactly one half of a circle and there aren't any on the a football pitch.
All players, except the penalty taker must be at least 10 yards away from the penalty spot when the penalty is taken. As the Penalty Area extends 18 yards from the goal line, and the Penalty Spot is 12 yards from the goal line, the distance from the Penalty Spot to the edge of the Penalty Area can be as little as 6 Yards. The Arc - not half circle - marks the area outside the Penalty Area, that is within 10 yards of the Penalty Spot, and therefore outside which players must be when the penalty is taken
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
The football field itself is a rectangle. It is divided in half into two smaller rectangles. At the centre point, the centre circle is found. Within each half there is the penaly area - another rectangle. This has within it another smaller rectangle, the 6 yard box. At the edge of the penalty area is a semi-circle, which denotes where players have to stand when a penalty kick is being taken. At each of the four corner flags there is a quarter circle which marks where the ball can be placed for a corner kick.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
The radius, from the centre of a circle to it's edge.
Take the full circle and fold it in half by taking one edge and bringing it to the other side of the circle.
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.
If you mean a line that gous from the center of a circle to the edge of the circle, that is a radius.
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
Because when a penalty is taken all the other players cannot be inside this area or in the penalty box itself.
Radius is the distance from the center of a circle to the outer edge, the same as one-half of the diameter of a circle.
