Question

What is the DIAMETER of a circle that has a CIRCUMFERENCE of 8π cm?

Answer 1

Given:

• Circumference of circle = 8π

To find out:

Find the diameter of circle?

Formula used:

Circumference of circle = 2πr

Solution:

Circumference of circle = 2πr

⇒ 8π = 2πr

⇒ r = 8π/2π

⇒ r = 4 cm

Now,

Diameter = 2 × Radius = 2 × 4 = 8 cm
