of this circle is 10 inches, what
is the radius of the circle?


asap pls​

Answer 1

Answer:

r=12.7323

Step-by-step explanation:

We find out the arc length formula when multiplying this equation by Θ:

Θ=45 degrees=π/4

L = r * Θ

r=L/Θ=10/π/4=40/π=12.7323

this answer is for sector(part of a circle)
