\sf\Large{\underline{\underline{Answer:-}}}

We know,

• Cost of fencing per m = Rs.24

• Cost of fencing the circular field = Rs.5280.

• First, we've to find the circumference of that circular field.

So, circumference of circular field,

\begin{gathered}\\\;\sf{:\rightarrow\;\;=\;\bf{\dfrac{Total \; cost}{Rate \; of \; per \; m}\:}}\end{gathered}

\begin{gathered}\\\;\sf{:\rightarrow\;\;=\;\bf{\dfrac{5280}{24}\:}}\end{gathered} = 220m.

The circumference of the circular ground is 220m.

ATQ,

We know that,

circumference = 2\pi \: r

Substitute the value,

220 = 2 \times  \frac{22}{7}  \times r

 220 = \frac{44}{7}  \times r

220 \times 7 = 44 \times r

1540 = 44 \times r

 r = \frac{1540}{44}

r = \sf{\cancel\dfrac{1540}{44}} = 35

─────────────────────

∴ The radius of the circular field is 35m.
