Question

the curved surface area of cyclinder is 900cm and the radius of base is 14cm find the TSA of cylinder​

Answer 1

Answer:

Step-by-step explanation:

2πrh = 900cm sq.

2 × 22/7 × 14 × h = 900

88h = 900

h = 10.23cm

TSA = 2πr(r+h)

= 2 × 22/7 × 14(14+10.23)

88(24.2)

=2129.6cm sq.

Answer 2

SOLUTION:

Given: curved surface area of cylinder is 900 cm square

as we know the curved surface area of a cylinder = 2πrh

therefore, 2πrh= 900

=>2 × 22/7 × 14 × h = 900

=> 88h = 900

=> h = 10.2 cm

therefore,

TSA of cylinder = 2πr(h+r)

=> 2×22/7× 14 ( 10.2 + 14 )

=> 88 ( 24.2)

=> 2129.6 cm^3

which is the answer ..
