Answer: Circumference = 15.7 ft ✅

Step-by-step explanation:

Do you need to know the circumference of a circle with a diameter of 5 ft? No problem! Luckily, there's a formula to find it! (:

Circumference

Let's work out the circumference. This is the formula that is going to help us. $\rightsquigarrow\boldsymbol{C=\pi d}$ C=circumference π=pi d=diameter

Now, stick in the values (note that we can use 3.14 for pi; pi is irrational, so we use 3.14 instead of pi to avoid irrational numbers)

$\boldsymbol{C=3.14\cdot5}$. Upon simplifying we obtain

$\boldsymbol{C=15.7\;ft}$. Which is our final answer.

Answer 2

Answer: 15.7

Step-by-step explanation:

$C=\pi d\\\\C=5\pi$

Using $\pi=3.14$, we get $C \approx 5(3.14)=\boxed{15.7 \text{ ft}}$
