57 in² The answer above is correct. Here is the formula Area of a circle = pi X r2 r = radius = 1/2 X diameter pi = 3.1416

If you mean a circle with a diameter of 28 cm, the circumference is 87.96459430051421067695392... using pi to 23 decimal places.* * * * *The answer above implies that the diameter of the circle was measure to an accuracy of 23 decimal places. Very unlikely, I suggest!

Pi ( 3.142 approx.) is the amount of times the diameter of a circle can be measured along the circumference of a circle. We know that Pi multiplied by the diameter of the circle is equal to it circumference. So we write C=PiD This means, as it says above, that a certain number of "Pi's" will be equal to the circumference.

pi*radius2 = 1693.14 square inches Make the radius the subject of the above then double for the diameter diameter = 46.430 inches to 3 decimal places

Circumference is equal to Diameter x Pi. So the circumference is 10π

If available, a protractor or a right drawing triangle can be used. If restricted to ruler and compass, a right angle can also be constructed to a given line segment by drawing a circle, with a radius less than the length of the line segment but more than half that length, with each end of the line segment as a center and connecting the two points of intersection of the two circles above and below the line. The line connecting to two intersections of these circles will form as right angle to the line segment.

Let us assume you have a circle drawn with the center identified. Then draw one straight line through the center. Measure the length of the line bound by the intercepts of the straight line with the circumference of the circle. The line segment is the diameter. Another case would be that you have a circle drawn with no center marked. Draw one straight line through the circle. Use a compass to draw the perpendicular bisector of the line segment bound by the intercepts of the straight line with the circumference of the circle toward the inner circle (the center of a circle cannot lie outside the circle!). Repeat drawing another (different) straight line through the circle and finish with a perpendicular bisector. The two bisectors will intercept at the center of the circle. Then you can proceed the same way as described in the first paragraph above. Hint to draw a perpendicular bisector of a line segment: take one end of the compass, pivot the point at one end of the line segment and mark an arc with the other end on both sides of the line. Move the compass and pivot one point at the other end of the line segment. Mark an arc with the other end on both sides of the line. If the procedure is done correctly, the two arcs, one from each end, should intercept on one side of the line. There is another intercept of the two arcs on the side of the line. Connect the two arc-intercepts with a straight line. Convince yourself that the line bisects the straight line at a right angle. This last line is the perpendicular bisector of the original line (The first and last lines form the perpendicular bisector of one another). ===================

Set a compass to draw a circle with a radius that's more than half the length of the line segment but less than the whole length.Put the compass point at one end of the segment and draw an arc above the middle of the segment and another below the middle of the segment.Put the compass point at the other end of the segment and again draw arcs above and below the middle of the segment, intersecting the first two arcs.Draw a line connecting the point where the two arcs intersect above the segment and the point where they intersect below the segment.That's your perpendicular bisector.

Area: pir*radius2 = 201 Making the radius the subject of the above gives it a value of 7.99876785 feet and double this is 15.9975357 or about 16 feet which is the diameter.

You can make a Diglett. Step 1: Draw a ground. Step 2: In the ground, draw half a circle. Step 3: Draw a circle in the haif circle. Last step: Now Draw eyes above the circle. Now you got a Diglett!
