Question

What's the circumference of a circle with a diameter of 9 inches?

Answer 1

Answer:

C = 28.26 in

Step-by-step explanation:

the circumference (C) is calculated as

C = πd ( d is the diameter ) , then

C = 3.14 × 9 = 28.26 in

                 What's the circumference of a circle with a diameter of 9 inches?

$\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}$

  We are asked to find the circumference of a circle, which we can find using the following formula:-

$\bold{Circumference{(circle)}=\pi d}$

• Where:-
• π=pi [3.14…]
• d=diameter (9 inches)

How to solve for circumference:-

• Replace d with 9 and multiply:-

$\hookrightarrow\sf{C=3.14\times9}$

$\bigstar$ On simplification,

$\hookrightarrow\sf{C=28.26\:inches}$

Notice that we are not asked to round our answer, so we leave it like that - C=28.26.

Good luck with your studies.
