A bus stup is barricaded from the remaining part of the road, by using 50 hollow cons made of rectucled cardboard. Each cone has base diameter of \( 40 \mathrm { cm } \) and height \( 1 \mathrm { m } \). If the outer side of each of the cones is to be painted and the cost of painity \( \mathrm { i } \). \( £ 12 \) per \( \mathrm { m } ^ { 2 } \). what will be the cost of painting all these cones? (Use \( \pi = 3.14 \) and take \( \mathrm { ck } \) ell \( \mathrm { ske } \). \( \sqrt { 1.04 } = 1.02 \)
