Answer:

C = 2πr

52.8 = 2πr

52.8/2 = πr

26.4 = 22r/7

26.4×7/22 = r

8.4cm = r

d = 2r = 2×8.4cm = 16.8cm

Diameter = 16.8cm

\huge{\pink{\underline{\underline{Answer -}}}}

circumference \:  \: of \:  \: a \: \:  circle \:  = \pi d

Let us assum the value of pie be \frac{22}{7}

Let the diameter be \huge\red{x}

\orange{\underline{\underline{Therefore}}}

 52.8\: = \frac{22}{7} \times x

{\red{x}} \: = \:  52.8 \times \frac{7}{22}

 {\red{x}} \: = \: \frac{369.6}{22}

 {\red{x}} \: = \: \frac{369.6 \times 10}{22 \times 10}

 {\red{x}} \: = \: \frac{3696}{220}

 {\red{x}} \: = \: 16.8
