AnSwer -:
CSA or Curved Surface Area of
cylinder-: 1452 sq. cm
Total Surface Area or TSA of
cylinder-: 4224 sq. cm
_______________________________
Explanation-:
Curved Surface Area (CSA) of cylinder-:
“CSA = 2 π r h”
Total Surface Area (TSA) of cylinder-:
“TSA = 2πr (h + r)”
CSA = Curved Surface Area
π = 22/7 or 3.14
R = radius
H = height
TSA = Total Surface Area
_______________________________
Given,
The radius of cylinder-: 21 cm
The height of cylinder-: 11 cm
To find ,
CSA and TSA of cylinder
_______________________________
Now ,
Curved Surface Area (CSA) of cylinder-:
“CSA = 2 π r h”
CSA = Curved Surface Area
π = 22/7 or 3.14
R = radius = 21 cm
H = height = 11 cm
Then ,
2 π x 21 x 11
2 x 22/7 x 231
2 x 22 x 33
44 x 33
= 1452 sq . cm
Then ,
CSA or Curved Surface Area of
cylinder-: 1452 sq. cm
Total Surface Area (TSA) of cylinder-:
“TSA = 2πr (h + r)”
π = 22/7 or 3.14
R = radius = 21 cm
H = height = 11 cm
TSA = Total Surface Area = ??
Now ,
2 π x 21(11 + 21)
2 x 22/7 x 21 (11+21)
2 x 22 x 3 (11+21)
44 x 3 (11 + 21)
44 x 3 x 32
132 x 32
= 4224 sq. cm
Then ,
Total Surface Area or TSA of
cylinder-: 4224 sq. cm
Hence ,
CSA or Curved Surface Area of
cylinder-: 1452 sq. cm
Total Surface Area or TSA of
cylinder-: 4224 sq. cm
