The width and circumference is 10 yards
Depends what size the ball is.
The corner arc has a radius of 1 yard with a center on the intersection of the goal line and the touch line.
They must be at least 10 yards from the corner arc. Note that the arc is 1 yard in radius so they must be 11 yards from the corner itself.
The ball must be placed on the field of play and either inside of or on the corner arc.
That is the penalty arc. Its center is the penalty mark and has a radius of 10 yards. During a penalty kick, all non-kicking players must be outside of the penalty area and also the penalty arc at the moment of the kick.
area of an arc =lenght of arc *radius/2
The radius is the distance between the centre of a circular arc and a point on the arc.
you will need to know the angle subtended by the arc; arc length = radius x angle in radians
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
The arc length is the radius times the arc degree in radians
the formula for the arc of a triangle is the arc length is equal to the angle times the radius. s=arc length theta=angle made y length of the arc lenth r=radius s=theta times radius
A special kind of direct free-kick given to an attacking team when a defender kicks, heads, or otherwise deflects the ball over his own goal line (not between the posts). It is taken from the corner arc, which is a quadrant with a radius of one yard. There is a corner arc marked in all four corners of the pitch. All defending players must retreat a minimum of ten yards from the corner arc, which is why there may be two small lines drawn off the pitch ten yards from the corner arc, to aid the referee to determine that defending players have retreated by the correct distance. A player cannot be offside directly from a corner kick. Even if anybody could kick that far, an own goal scored directly from a corner would be disallowed. The linesman should step back a few paces in order to allow the taker of the corner to get a run-up to the ball.
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.
