Answer: first option.
Step-by-step explanation:
Find the common difference d of the arithmetic sequence:

Then the formula for the 101st term is the shown below:

Where:

Substitute values into the formula. Therefore, you obtain:

We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²
To find slope, it's rise over run, so the answer would be 2/36, simplified to 1/18.
Answer:
c. dividing is the inverse of multiplying because it doesn't really relate the equation like the others do.
