Question

the volume of a cylinder is 308cm. its height is 8 cm.find its lateral surface area and total surface area​

Answer 1

Answer:

GIVEN

Step-by-step explanation:

GIVEN THE VALUE OF = PIE.R2.H=308

THEN WE FIND OUT VALUE OF REDIUS  22/7*R2*8= 308

THEN THE REDIUS IS 7/2

SURFACE AREA 2PIE.R.H= 2*22/7*7/2*8= 176

AND THE TOTAL SURFACE AREA IS 2PIE.R(R+H)

   2*22/7*7/2(8+7/2)

=253

Answer 2

volume of cylinder (V) =πr²h=308cm³

22/7*r²*8=308

r²=(308*7)/(22*8)

=2*22/7*7/2*8

=178 cm²

total surface area​(TSA)=2πr(r+h)

=2*22/7*7/2(7/2+8)

=253cm²
