Question

In circle P, diameter QS measures 20 centimeters. Circle P is shown. Line segment Q S is a diameter. Line segment R P is a radius. Angle R P S is 123 degrees. What is the approximate length of arc QR? Round to the nearest tenth of a centim

Answer 1

Answer:

9.9 cm

Step-by-step explanation:

As we can see in the diagram that the total of straight line has 180 degrees

Therefore ∠RPQ is 180 degrees - 123 degrees = 57 degree

And, arc length is equivalent to the circumference of circle i.e

$= 20\pi \times \frac{57}{360}$

where,

Pie = 22 by 7

Therefore the approximate length of QR is 9.9 cm

We simply applied the above calculation so that we get to know the length and the same is to be considered
