A convex polygon
Hope this helps :)
X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
We have that
Area=pi*r²
D=24 in------------ > r=D/2=24/2=12 in
Area =pi*12²=452.16 in²
the circumference=2*pi*r=2*pi*12=75.36 in
the answer is
the area is 452.16 in² and the circumference is 75.36 in
Answer:
I'm not sure about "11" but 12. is "by the definition of right angles", and 16. is "by the SAS(side angle side) congruency theorem"
