Answer:

Area of circle =

\pi \: r {}^{2}

Step-by-step explanation:

here we know,

r =  \frac{d}{2}  \\   \:  \:  \: =  \frac{200}{2}  \\   \:  \:  \: = 100

area \: of \: circle \:  = \pi \: r {}^{2}  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =   \frac{22}{7}  \times (100) {}^{2}  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{22}{7}  \times 10000 \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 31428.57

therefore the answer is

area of circle is 31428.57 cm2
