area of circle = 22/7 x 10.5 x 10.5 = 346.5 sq cm

346.5 / 8 = 43.3125 sq cm

therefore area of each piece is 43.3125 sq cm

=> area of the whole pizza = pi * (r)sq. = 22/7 * 21/2 * 21/2 = 693/2 = = 346.5 sq. cm

therefore,

total area of 8 equal sectors = area of the pizza

=> area of 1 sector or each sector (since they are equal) = area of the whole/8

= 346.5 / 8 = 43.3125 sq.cm
