Question

The circumference of a circle is 20435 cm. What is the approximate diameter of the circle? Use 227 for π. Enter your answer as a mixed number in simplest form in the box. cm

Answer 1

Explanation:

We know the formula for circumference is C = πd (Circumference = π x diameter). Using substitution, you could work it out like so:

C = 20435

π = 227

20435 = 227 x d

which means:

20435/227 = d (this fraction cannot be simplified)

That should be roughly 90 5/227 cm as a mixed number
