Question

What is the approximate length of the radius r?

Answer 1

Answer:

Circ = 2 x pi x r

28.3 = 2 x 3.14 x r

r = 28.3 / (2 x 3.14) = 4.51 cm

r = 4.5 cm

Step-by-step explanation:

Answer 2

Answer:

4.5 cm

Step-by-step explanation:

The formula to find the radius of a circle is

$r=\frac{c}{2\pi }$

$r=\frac{28.3}{2\pi }$

$r=4.5 cm$
