Question

Find the diameter of the circle with the given circumference. Use 3.14 for pi. C=19 cm

Answer 1

6.051cm, or 6cm rounded

Explanation:

First we have to find the radius given the circumference.

The formula for radius:

r = C/2π

19 / (2 × 3.14) = 3.025

Then we can use the radius to find the diameter.

The formula for diameter:

d = 2 × r

2 × 3.025 = 6.051

Answer 2

hello,

`D = (C)/(\pi) \\ \\ D = (19)/(3.14) \\ \\ D = 6.05 \: cm`
