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

`\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}`

Formula for Circumference:-

`\bigstar\boxed{C=\pi d}}`

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:-

`\sf{C=(3.14)(8)}`

Multiply:-

`\boxed{\sf{C=25.12\:inches}}`

Good luck.

Answer 2

25.12 inches

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.
