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 related to the radius $r$ by the formula $d = 2r$. Given $r=11.3$ cm, so $d = 2\times11.3$.
$d=22.6$ cm

Step2: Find the circumference

The formula for the circumference $C$ of a circle is $C = 2\pi r$ or $C=\pi d$. Using $\pi\approx3.14$ and $d = 22.6$ cm, we have $C=3.14\times22.6$.
$C = 70.964$ cm

Answer:

Diameter: 22.6 cm, Circumference: 70.964 cm
