Ok, so;
Let me draw the figure here below:
We know that the area of a circle can be found using the next equation:
Area = πr².
Where r is the radius and π is a number.
So, the area of this circle, will be:
Area = π(1km)²
Area = π km²
Yes that’s the correct answer one is congruent to the other
B and C
Then do D
Hoped this helped
The equation only has 1 solution which is 2.
Answer is
= 1.24*5+1.1*2.20+4.5*0.68
= <u>11.68</u>
