[tex]\blue\textsf{\textbf{\underline{\underline{Question:-}}}}[/tex]
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.
