The diameter of a circle is 8 in. What is its circumference?

[tex]\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]

Formula for Circumference:-

[tex]\bigstar\boxed{C=\pi d}}[/tex]

Where

  • C = Circumference
  • π = pi (we're asked to use 3.14 for pi, so we'll do that)
  • d = diameter (we're given that it's equal to 8 in)

Substitute the values:-

[tex]\sf{C=(3.14)(8)}[/tex]

Multiply:-

[tex]\boxed{\sf{C=25.12\:inches}}[/tex]

Good luck.

Answer:

25.12 inches

Step-by-step explanation:

Given that,

→ Diameter = 8 in

→ Radius (r) = 8/2 = 4 in

→ π = 3.14

Formula we use,

→ 2πr

Then the circle's circumference is,

→ 2πr

→ 2 × 3.14 × 4

→ 2 × 12.56

→ [ 25.12 in ]

Thus, circle's circumference is 25.12 in.
