-- Draw a line from the center of the circle to the end of the horizontal rail-platform.
That line is a radius of the circle, so it's 1/2 the length of the diameter.
-- Draw a line from the center of the circle straight down, perpendicular to the
horizontal rail-platform.
Now you have a right triangle inside the circle. The hypotenuse is a radius of the circle ...
you know it's length. The base is 1/2 of the rail platform ... you know how long that is.
So you have 2 sides of the right triangle.
-- Now you can calculate the 3rd side of the right triangle. That's the triangle's height,
and it's the vertical distance from the rail platform to the center of the circle.
-- Plus one more radius of the circle takes you the rest of the way to the top of the tunnel.
Thank you. You've been a great audience. I'm here til Friday.
Drop a TP in the jar, and don't forget to tip your waiter.
A CIRCLE.
There's no such thing as the "area of a circumference", no matter how you spell it.A circumference is a length, representing the distance around a circle, and doesn'thave an area.If you know the circumference of a circle, and you call it 'C', then the area of the circle isC2 / (4 pi)

Do u mean a circle with a horizontal bar at the bottom? if is then that's a CARTOUCHE. .

To calculate the area of a circle use this formula: pi x r2.
To make perpendicular lines, draw a horizontal line. Then using a compass or tracing around the edge of a curved object, draw one circle ( or just a semi-circle) so that it crosses the horizontal straight line in at least one point. Now rotate the compass or move the curved object to draw another circle (or semi-circle). This second circle (or semi-circle) must cross through the horizontal straight line as the first one did. It also must cross through the first circle (or semi-circle) at two points- above the horizontal straight line and below the horizontal straight line. Next, draw a straight line from where the two circles (or semi-circles) meet above the horizontal straight line through to where they meet below the horizontal straight line. You now have a line perpendicular to the first line.
