What is a segment whose endpoints are on a circle?
A chord. a diameter also has endpoints on a circle, the only difference is a diameter goes through the center point and a chord doesnt have to go through the center. a diameter is considered a chord.
How many feet go around a 20 ft circle?
The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. In this case, the radius is half of the diameter, so for a 20 ft circle, the radius would be 10 ft. Plugging this value into the formula, we get C = 2 x 3.14159 x 10 = 62.8318 ft. Therefore, approximately 62.83 feet would go around a 20 ft circle.
What is the best estimate of the circumference of a circle 2 units?
The Circumference of a circle (C) equals the number "pi" times the diameter of the circle (d). "pi" (3.14159...) is a number which you can never find the value of precisely, the numbers after the decimal point go on for ever. Given this information you can calculate what you need to know about your circle.
What is the formula for sine?
Sin, Cos and Tan is the formula for sine. A right-angled triangle is a triangle in which one of the angles is a right-angle. The hypotenuse of a right angled triangle is the longest side, which is the one opposite the right angle. The adjacent side is the side which is between the angle in question and the right angle.
