The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm

5. yes because it passes the vertial line test. it is linear
Four multiplied by four is 16
Answer: 9072
Step-by-step explanation:
It seems that the number of cans that grades 1 and 2 collect are irrelevant in the problem so you can basically ignore that. Grades 3 and 4 have 6683 cans which is 2389 cans less than grades 5 and 6 so that means grades 5 and 6 have 2389 cans more than 6683. Now you just add 6683 and 2389 to find the cans that grades 5 and 6 have.
6683 + 2389 = 9072
Grades 5 and 6 have 9072 cans

Answer:
:)
Step-by-step explanation:
The question is asking for the square root of twelve.
If you multiply the 2 and 6, you get twelve.
Simplofy the fraction, you get one half.
If something is to the power of one half, we need the square of it. Yet 12 does not have a square root so you decide your format of answer, under a radical, or to the power of one half.
