It should be 44ft bc 22ft and 22ft is 44ft
The pertinent formula for the circumference of a circle with diameter d is
C =pi*d.
Thus, if the dia. is 6 inches, the circumf. is C = 6pi inches. Alternatively, if we let pi = 3.14, the circumf. is C = 6*3.14 (answer A).
Answer: 5
Step-by-step explanation:
Answer:
x=9,-1 and 
Explanation:
we have been given with the quadratic equation 
we compare the given quadratic equation with general quadratic equation
general quadratic is 
from given quadratic equation a=1,b= -8,c= -9
substituting these values in the formula for discriminant 

Now, to find the value of x
Formula is 
Now, substituting the values we will get

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of
