Question

The circumference of a circle is 63.80 inches radius of the circle?

Answer 1

Answer:

2πR is the circumference of circle formula.

=> 63.80 inches= 2*22/7*R ( as we know π is equal to 22/7)

=> 63.80 inches= 44/7* R

=> 63.80 inches= 6.2857*R

R= 63.80/ 6.2857

R= 10.15 inches

therefore your answer will be 10.15 inches as radius

Answer 2

Answer:

Radius is 10.15 inches .

Explanation:

Given -

Circumference of circle is 63.80 inches

To find -

The radius of circle

Solution -

As we know that,

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

Where,

r is radius of circle.

Put the given values in these formula we get

63.80 = 2\pi \times r[/tex]

$\frac{63.80}{2\pi}  = r$

$\frac{31.9}{\pi}  = r$

The value of π is 3.14 .

$\frac{31.9}{3.14}  = r$

$r = 10.15$

So,

Radius is 10.15 inch.
