Diameter of the bigger semi-circle is 15 m
circumference of the bigger semi-circle = πd = 15π
diameter of the smaller semi-circle = 15 - 2(1.25) = 15 - 2.5 = 12.5 m
circumference of the smaller semi-circle = πd = 12.5π m
Total length of the segments between the two circles = 11(1.25) = 13.75 m
Total length of wrought iron used = 15π + 12.5π + 13.75 = 100 m
Two lines are perpendicular if and only if the two lines intersect at right angles. If a point is in fourth quadrant,then it coordinates at negative. If thecoordinates are negative, then thepoint is in the fourth quadrant. If a figure is a triangle, then it has three sides.
