    Question is very simple awsome.

    hope you got it.

    please follow meee.

    Step-by-step explanation:

    height=32cm

    radius=10.5cm

    curved surface area of the cylinder =2πrh (formula)

    curved surface area of the cylinders =2×22/7×10.5×32

    =2×22/7 (7 cut ho gaye hai) 10.5 (se cut ho gaye hai) ×32

    =2×22×15×32

    =21120cm 2

    Total surface area of the cylinders=2πr(r+h) (formula)

    =2×22/7×10.5(10.5+32)

    =2×22/7 (7 cut ho gaye hai) 10.5 (se cut ho gaye hai) (15+32)

    =2×22×15(15+32)

    =660(15+32)

    =600×47

    =28200
