Question

find the missing measurements for each circle. you can use 3.14 as an approximation for pi. circle e has a radius of 11.3 cm. find the length of the diameter and the approximate circumference of the circle. radius (cm) diameter (cm) circumference (cm) 11.3

Explanation:

Step1: Find the diameter

The diameter $d$ of a circle is twice the radius $r$. Given $r = 11.3$ cm, so $d=2r$.
$d = 2\times11.3=22.6$ cm

Step2: Find the circumference

The formula for the circumference $C$ of a circle is $C = \pi d$. Using $\pi\approx3.14$ and $d = 22.6$ cm, we have $C\approx3.14\times22.6$.
$C\approx70.964$ cm

Answer:

Diameter: 22.6 cm, Circumference: 70.964 cm
