I think it’s the last one I’m not sure tho :)
The answer is 28.27 cm because the formula for area of a circle is A=

*r^2. Hope this helped!
Answer:
256m^2.
Step by step:
Well now let’s find the area of a square which is 8*8 = 64.
And now let’s find the area of a triangle using the formula 12*8 / 2 = 48.
And since there is 4 sides we multiply 48 by 4 which is 192.
so 192 + 64 is 256m^2.
Answer:
x^2 -12x+20
Step-by-step explanation:
If the zeros of the functions are at 10 and 2
(x-10) (x-2)
FOIL
x^2 -2x-10x+20
Combine like terms
x^2 -12x+20
