Answer:
SA = 156π
Step-by-step explanation:
The formula for surface area of a cylinder is
SA = 2πr² + 2πrh where r is the base radius, and h is the height.
We are given r = 6 and h = 7. Plug in those values and evaluate...
SA = 2π(6²) + 2π(6)(7)
SA = 2π(36) + 2π(42)
SA = 72π + 84π
SA = 156π

GIVEN :-
RADIUS = 6 UNITS
AND
HEIGHT = 7 UNITS.
→ Surface area of of cylinder = 2πr² + 2πrh
→ 2πr(r+h)
→ value of π is 22/7
put the value of π
[tex] \sf \implies \: 2 × \frac{22}{7} × 6×(6+7) [/tex]
[tex] \sf \: \implies \: 2 \times \frac{22}{7} \times 6(13)[/tex]
[tex] \sf \implies \: \frac{44}{7} \times 78[/tex]
[tex] \huge \sf \implies \frac{3432}{7} [/tex]

HENCE ANSWER IS 49.285 UNITS
