Answer:

100 pie m^2


solution \\ diameter = 20 \: m \\ radius = (20)/(2) = 10 \: m \\ area \: = \pi \: {r}^(2) \\ \: \: \: \: \: \: \: \: \: \: \: = \pi * {10}^(2) \\ \: \: \: \: \: \: \: \: \: \: = \pi * 100 \\ \: \: \: \: \: = 100\pi \: {m}^(2) \\ hope \: it \: helps....

Answer:


= 100\pi {m}^(2) \\

Explanation:


d = 2r \\ 20 =2 r \\ (20)/(2) = (2r)/(2) \\ r = 10


area = \pi {r}^(2) \\ = \pi * 10 * 10 \\ = 100\pi {m}^(2)

hope this helps
