Question

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

Answer 1

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

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

$\sf \implies \: 2 × \frac{22}{7} × 6×(6+7)$

$\sf \: \implies \: 2 \times \frac{22}{7} \times 6(13)$

$\sf \implies \: \frac{44}{7} \times 78$

$\huge \sf \implies \frac{3432}{7}$

$\huge \bf \implies49.285$

HENCE ANSWER IS 49.285 UNITS

Answer 2

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
