DIRECT ANSWER
Total Surface Area (CSA) will be - 36,960cm²
Curved Surface Area (TSA) will be - 6,160cm²
FULL EXPLANATION
Total Surface Area
Formula = 2 π r ( r+h )
= 2 × 22/7 × 70 (70+14)
= 440 × 84
= 36,960cm²
Curved Surface Area
Formula = 2 π r h
= 2× 22/7 × 70 × 14
= 44 × 140
= 6,160cm²
PLEASE MARK AS BRAINLIST, I HAVE NOT COPIED THIS ANSWER FROM SOMEWHERE, I HAVE DONE THIS BY MYSELF
