Question

What’s the approximate circumference of a circle with radius 10 feet?

Answer 1

Answer: C≈62.83ft

Step-by-step explanation:

simply take your radius and times it by 2 and you get 20. then times twenty by pi.

Answer 2

Approximate circumference of circle is $20\pi$ feet that is 62.8 feet.

Solution :

Need to determine approximate circumference of a circle with radius as 10 feet.

So given that radius of circle = 10 feet

Circumference of circle is product of constant $2\pi$ with radius of circle r.

=> Circumference of circle = $2\pi r$

On substituting the value of radius, we get circumference

So circumference of a circle of radius 10 feet = $2\pi \times 10 = 20\pi$

Taking $\pi$ = 3.14, we get circumference = 20 x 3.14 = 62.8 feet  

Hence approximate circumference of circle is $20\pi$ feet that is 62.8 feet.
