Circle Test

True or False: A diameter is a chord.

• True

• False

What is the formula for? (^angle/₃₆₀)Πr²

• arc length

• area of a sector

• area of a segment

• arc measure

True or False: A chord is a line

• True

• False

What is the difference between arc length and are measure

• Arc length is the distance of the arc measures in linear units (ft, in, m, etc) whereas arc measure equivalent to the measure of the central angle creating the arc measured in degrees.

• Arc measure is the distance of the arc measures in linear units (ft, in, m, etc) whereas arc length equivalent to the measure of the central angle creating the arc measured in degrees.

• They are the same thing.

Which is the standard equation for a circle?

• (x-h)²+(y-k)²=r

• (x-h)²+(y-k)²=r²

• (x+h)²+(y+k)²=r²

• (x+h)^2-(y+k)²=r

Which are true? (MORE THAN ONE)

• A chord has two endpoints on a circle

• A diameter has two endpoints on a circle

• A secant has two endpoints on a circle

• A tangent has two endpoints on a circle

What is the difference between a secant and a tangent

• A tangent is a line and a secant is a line segment

• A tangent passes through a circle once and a secant passes through the circle twice.

• A secant and a tangent are both chords but a tangent goes through the center of the circle

• A secant passes through the circle once and a tangent passes through the circle twice.

What is the formula for? (^angle/₃₆₀)2Πr

• arc length

• area of a sector

• area of a segment

• arc measure

Which of these are by definition line segments?

• Tangent

• Chord

• Diameter

• Radius

• Secant

If you are given the endpoints of the diameter of a circle, what do you use to find the center?

• Distance

• Midpoint

• You can't find the center
