Question

the area of the base of a right circular cylinder is 154 cm square and its height is 8 cm find the curved surface area of the cylinder

Answer 1

Answer:

curved surface. area of cylinder =2πrh

Step-by-step explanation:

2πr=154

h=8

2πrh=154×8=1232 cm sq

Answer 2

Answer:

Step-by-step explanation:

we know that the area of a cylinder is 2πr²h by using that we find the radius

2πr² = 2*22/7*r²*8

⇒ r = 7/4

now using the CSA of cyclinder

2πrh = 2×22/7×7/4×8

∴ area = 88cm²
