circumference is the outside of a circle. perpendicular is a horizontal line which touches a vertical line. verticy is the corner of a shape. segment is a small part of a circle. arch is a small part of the circumference. acute is an angle smaller than 90 degrees. obtuse is a angle larger than 180 degrees.
What is a true statement about a circle inscribed in a regular polygon?
The circle has a smaller area than the polygon.
When looking at a curve smaller than a semi circle you use angle bisectors to find the rest of the circle?
wee
When looking at a curve smaller than a semicircle you use angle bisectors to find the rest of the circle true or false?
false
What A circle with a radius of 3 cm shares a center with another circle that has a radius of 5 cm. Find the probability that a randomly selected point is in the larger circle but not in the smaller ci?
We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.
