Question

What is the the radius and diameter of the circumference, 60.8cm?

Answer 1

We are using the formula of Circumference :

$\sf \: Circumeference_{(Circle)} = 2 \pi \times r$

Putting values according to question,

$\sf \: Circumeference_{(Circle)} = 2 \pi \times r = 60.8cm$

$\sf \: Circumeference_{(Circle)} = r = \frac{60.8}{2 \pi }$

$\sf \: Circumeference_{(Circle)} = 9.68cm$

So now we know the radius so we can find the diamter now easily :

$\sf \: Diameter=2r$

$\sf \: Diameter=2 \times 9.68$

$\frak \pink{\: Diameter = 19.36cm}$
