3420°
explanation:
the equation of the sum of interior angles are (n-2)x180
polygon above has 21 sides so you sub n as 21 and plug the equation in the calculator
Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation:
4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS;
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this;
4x − 2(5x − 1)
= 4x - 10x +2
= -6x + 2 or 2 - 6x
We see that the solution give is false.
The formula for circumference is C= 2(pi)(r)^2. Because diameter is double the radius, and the diameter is 8 ft, the radius is 4 ft. So, plug that into the equation, and you get: C=2(pi)(4)^2. The answer is 32 pi ft. If the question asks for the exact answer, keep the pi as it is, but if it says to round, multiply 32 by pi and round.
