The diameter of the circle is 15.99cm.
Answer:

Step-by-step explanation:
The sum of the interior angles of a polygon with
sides is
. Since the shape in the figure has 5 sides, the sum of its interior angles is
.
Therefore, we can set up the following equation:

Since
and
make up one side of a line, they are supplementary, as each side of a line is
.
Thus, we have:

Answer: Formula one= P = 2 ( l+width) units where
“l” is the length of the rectangle
“b” is the width of the rectangle
Formula 2 = P = 2(l) + 2(w)
Step-by-step explanation:
R=-7, you have to put each answer in the equation, therefore; 21=42-3(-7) So you have to do multiplication (PEMDAS, if you arent aware of that acronym then it stands for the order of what to do with an equation, Parentheses get solved first, then Exponents, then multiplication, then division, then addition, then finally subtraction. Solving in that order will solve your answer correctly.) With -3 times -7 which gives you 21. Then you do 42 - 21 which equals 21. So 21 = 21.
Answer:
A
Step-by-step explanation:
Each hour is 30 degrees. 11 to 6 is 7 hours so 30 * 7 = 210 degrees, which is greater than a semicircle, which is 180 degrees.
