Question

the cercumference of the base of cylinder is 44cm amd height is 10cm then find its csa

Answer 1

Circumference = 44cm.

ie; 2πr =44
44/7 r =44.
=r= 44×7/44
=7cm.

Csa of cylinder = 2πrh.
= 2×22/7×7×10
=440cm squared.


Hope that helps.

Answer 2

circumference if the base = 44cm
C.S.A of the cylinder = 2πrh
h= 10cm
r= ?
formula of the circumference = 2πr
2πr= 44
2×22/7×r= 44
r = 44×7/2×22
r= 7 cm

so C.S.A= 2×22/7×7×10
= 2×22×10
= 44×10
= 440 cm square answer....
