Explanation: formula of a circle
A= pi r ^2
<span>As we know that 1 µm = 10^-6 m On squaring both sides 1 µm2 = 10^-6 x10^-6 m2 1 µm2 = 10^-12 m2</span>
Answer:
correct
Step-by-step explanation:
i think correct,but maybe i am wrong
The Answer Is 18
Order Of Operation laws says that you must do the parentheses first, 45x2.
45x2=90
The next thing you must do is divide 90 by 10 since division is before addition.
90/10=9
Now combine like terms.
9+9=18
A suitable calculator can row-reduce the augmented matrix.
