Answer:

A=530.66\ in^2

Step-by-step explanation:

The circumference of a dartboard, C = 26pi inches

We need to find the area on which the dart may land.

The circumference of a circle is given by :

C = 2πr

Where

r is the radius of the dartboard

r=\dfrac{C}{2\pi}\\\\r=\dfrac{26\pi}{2\pi}\\\\r=13\ in

Now, the area of a circle is given by :

A=\pi r^2\\\\=3.14\times (13)^2\\\\A=530.66\ in^2

so, the required area is 530.66\ in^2.

AURORKA [14]
To solve this problem we can use simple proportion
If 
270$ -------------------------3000 pesos
x $  ---------------------------100 pesos               (x$ means that we dont know how much)
Now we crossmultiplying to get proportion
x*3000=270*100
Now we just to solve eq
3000x=27000  /:3000
x=27000:3000
x=9$ - its the result
