stepladder [879]

Answer: $3\dfrac{11}{20}\ \text{miles}$

Given

Elisa run a total of $8\frac{4}{5}$ miles on Saturday and Sunday.

If she runs $5\frac{1}{4}$ miles on Saturday

Then, distance traveled on Sunday is given by

$\Rightarrow 8\dfrac{4}{5}-5\dfrac{1}{4}\\\\\Rightarrow \dfrac{44}{5}-\dfrac{21}{4}\\\\\Rightarrow \dfrac{44\times 4}{5\times 4}-\dfrac{21\times 5}{4\times 5}\\\\\Rightarrow \dfrac{71}{20}\\\\\Rightarrow 3\dfrac{11}{20}\ \text{miles}$

So the radius of this circle = 1/2 * 2 = 1.

The required area = π * 1^2

= π units^2.
