Question

C is the center of the circle. Find the length of QPR

Answer 1

Answer:

30

Step-by-step explanation:

The length from one point on the edge of a circle to the middle will always be the same otherwise it isn't a circle. If QC is the same as CR than 15 and 15 would get you 30.

Answer 2

Answer:

70.686

Step-by-step explanation:

In order to know the length of QPR, we have to notice that QR=1/4 of the perimeter of the circle (circumference), then QPR= 3/4 of the perimeter of the circle.

Remember:

Circumference of a circle= 2$\pi$*radius

Where:

$\pi$= 3.1416 (its a constant value)

radius=15

Circumference of a circle=2*3.1416*15=94.248

Then:

QPR= 3/4 of the circumference of the circle

QPR= 3/4*94.248

QPR= 70.686
