What is the distance in Centimetres between two parallel chords of lengths 32 cm and 24 cm in a circle of radius 20 cm?

= √400−256 = √144 = 12 cm. ∴ Required distance = EF = OF – OE = (16 – 12) cm = 4 cm.

How do you find the distance between two parallel chords?

If two parallel chords are on the opposite side of centre, then distance between two parallel chords is the sum of the distance from the centre to the chords. Q3. AB and CD are two parallel chords of a circle such that AB=10cm and CD=24cm.

What is the distance between two parallel chords of length 16 cm and 12 cm of a circle with radius 10 Centimetre?

Let O is center and r is radius of circle r = 10 cm chord AB = 12 cm and chord CD = 16 cm. and CQ = QD = 12 × CD = 12 × 16 = 8 cm.

What is the distance between two parallel tangents of a circle having radius 6.7 cm?

Thus, the distance between two parallel tangents of the circle is 9 cm.

How do you find the chord length of an arc?

Divide the central angle in radians by 2 and perform the sine function on it. Divide the chord length by double the result of step 1. This calculation gives you the radius. Multiply the radius by the central angle to get the arc length.

What is the length of a chord at a distance of 9cm from the center of a circle of radius 15cm?

distance of the chord from the centre is 9cm. Draw a perpendicular bisector from center to the chord and name it OC. The length of the chord is AC + BC = 12 + 12 = 24 cm.

What is distance between two parallel tangents of a circle of radius 7 cm?

Then, the distance between two parallel tangents of a circle of radius 7cm will be \bold{2*7=14\:cm.} 2∗7=14cm. Therefore, the right answer = 14 cm.

What is the distance between two parallel tangents of a circle having radius4 5 cm?

This can be seen as since tangents are parallel and both touches the circle at one point . Hence, we can say a length of Diameter will fulfill the perpendicular gap between them . So, Distance between two parallel tangents will be twice of length of radius or Diameter only.

How do you calculate chord length?

r is the radius of the circle. c is the angle subtended at the center by the chord. d is the perpendicular distance from the chord to the circle center….Chord Length Formula.

Formula to Calculate Length of a Chord
Chord Length Using Trigonometry	Chord Length = 2 × r × sin(c/2)
