Answer 1

$\huge\fcolorbox{black}{red}{Answer}$

Given :-

✫Radius = 7cm

✫Height = 10cm

Find :-

✫Curved surface area

✫Total surface area

✫Volume

Solution :

◑Curved surface area = 2πrh

⇛2×22/7×7×10

⇛20×22

⇛440cm²

Hence, The curved surface area of circular cylinder is 440cm²

◑Total surface area = 2πr(h+r)

⇛2×22/7(10+7)

⇛44×17

⇛748sq.cm

Hence, The Total surface area of circular cylinder is 748sq.cm

◑Volume = πr²h

⇛22/7×7×7×10

⇛1540cm³

Hence,The volume of circular cylinder is 1540cm³
