We know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm
the answer is
285.9 cm
The value of x would be 24 because all the sides added up must equal 72
Evan is the correct answer.
Answer:
x = 0 or x = -7
Step-by-step explanation:
Solve for x over the real numbers:
6 x^2 = -42 x
Add 42 x to both sides:
6 x^2 + 42 x = 0
Factor x and constant terms from the left hand side:
6 x (x + 7) = 0
Divide both sides by 6:
x (x + 7) = 0
Split into two equations:
x = 0 or x + 7 = 0
Subtract 7 from both sides:
Answer: x = 0 or x = -7
