Formula for the circumference of a circle = pi x 2 x radius

Circumference = 3

pi = 3.14

radius = r

---To find the radius, we will need to solve for it. Start by plugging in what we know.

3 = 3.14 x 2 x r

---Simplify by multiplying 3.14 by 2

3 = 6.28 x r

---Divide both sides by 6.28 to solve for r

r = 3 / 6.28 = 0.4777

---Round the decimal to the nearest tenth

r = 0.5

Hope this helps!

Answer:

r=0.5

Solution:

  • Circumference of a circle - C=2πr
  • Plug in the values we are given:
  • 3=2πr
  • Simplify:
  • 3=6.3r
  • Divide both sides by 6.3:
  • r=0.5

Hope it helps.
