Question

if the premiter of the bsse of the cylinder is 44 cm and its hight is 10 cm then find its csa​

Answer 1

Perimeter of the base of cylinder = 44 cm

Height of the cylinder = 10cm

C.S.A of Cylinder = 2πrh

=> C.S.A = 44 × 10 ( Perimeter = 2πrh )

=> C.S.A = 440 cm²

Answer 2

Answer:

perimeter of base = circumference

44 = 2πr

44x7/22x2 = r

308/44 = r

therefore.,7 = r

CSA of cylinder = 2πrh

= 2 x 22/7 x 10 x 7

= 2x22x10

= 440 Cm^2
