Question

A circle has a circumference of 8 centimeters. What is the circle's

Answer 1

Formula for the Circumference of a Circle = pi x diameter

---The diameter is the same thing as 2 x radius

Circumference = 8

pi = 3.14

Diameter = d

---First, plug in what we know

8 = 3.14 x d

---Divide by 3.14 to get d by itself

d = 8 / 3.14 = 2.54777

---Round to the nearest tenth

d = 2.5 cm

Hope this helps!

Answer 2

Answer:

d=2.5

Solution:

• Circumference:
• C=πd
• 8=πd
• Since we can't simplify this equation yet, we can divide both sides by 3.14 (which is the same as pi) in order to isolate d:
• 8÷3.14=d
• d=2.5

Hope it helps.
