When we speak of the word "perimeter" of a circle, we mean to say the circumference. Since we are only given a semicircle, the perimeter would be,
perimeter = (pi)(radius) + diameter
Substituting the known values,
perimeter = (3.14)(6 cm) + 12 cm
The value of the perimeter is,
perimeter = 30.84 cm
Answer:
m=4
Step-by-step explanation:
Since we know that quadrilateral ABCD is similar to QRST, we know that the side lengths will be proportional to one another. As such, we should take a ratio to determine the side length of m.
![\frac{ST}{CD}=\frac{RS}{BC}\\\\\frac{6}{15} =\frac{m}{10}\\](https://tex.z-dn.net/?f=%5Cfrac%7BST%7D%7BCD%7D%3D%5Cfrac%7BRS%7D%7BBC%7D%5C%5C%5C%5C%5Cfrac%7B6%7D%7B15%7D%20%3D%5Cfrac%7Bm%7D%7B10%7D%5C%5C)
