Answer 2

total ribs = 8
therefore, total sectors = 8
therefore, theta( sector angle) = 360÷8
=45 degree
area between two consecutive rings = area of a sector
$area \: of \: sector = \frac{\pi {r}^{2} }{ {360}^{0} } \times sector \: angle \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ \frac{22}{7} \times45 {}^{2} }{360} \times 45 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{45 \times 45 \times 45 \times 22}{360 \times 7} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22275}{28} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 795.54 {cm}^{2}$
