Question

Find the surface area of the cylinder. radius of 6. height of 7.

Answer 1

SA = 156π

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

Answer 2

`\huge \bf \red{ \mid{ \overline{ \underline{ANSWER}}} \mid}`

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

`\sf \implies \: 2 × (22)/(7) × 6×(6+7)`

`\sf \: \implies \: 2 * (22)/(7) * 6(13)`

`\sf \implies \: (44)/(7) * 78`

`\huge \sf \implies (3432)/(7)`

`\huge \bf \implies49.285`

HENCE ANSWER IS 49.285 UNITS
