Answer:
A= 254.34 m²
Step-by-step explanation:
to find area of a circle use this formula, A=
r²
now just plug it in
A= 9²
A=81
A= 254.34 m²

Hope this helps.
Each length is 72 times longer so the actual dimensions are 381.6cm by 576 cm
Answer:
C
Step-by-step explanation:
In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:
N1⋅N2=a⋅c=1⋅−12=−12
AND
N1+N2=b=−1
After trying out a few numbers we get N1=3 and N2=−4
3⋅−4=−12, and 3+(−4)=−1
x2−x−12=x2−4x+3x−12
x(x−4)+3(x−4)=0
(x+3)(x−4)=0
Now we equate the factors to zero.
x+3=0,x=−3
x−4=0,x=4
