Question

Find the total surface area of a cylinder with a radius of 5 meters and a height of 7 meters

Answer 1

Answer:

Total surface area = 376.8m²

Explanation:

radius = 5m

height = 7m

total surface area = 2π×r×h + 2π×r²

total surface area = 2π×r(h+r)

total surface area = 2×3.14*5 (7+5)

total surface area = 31.4 × 12

total surface area = 376.8m²

Answer 2

Given :

Find the total surface area of a cylinder with a radius of 5 meters and a height of 7 meters

How To Solve :

✷ Here we are provided with radius and height and we need to find the total surface area or T.S.A. of the cylinder by the formula then put the values of radius and height to get the required answer

Solution :

Given that :

Radius = 5 metres

Height = 7 metres

Formula for getting the T.S.A

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \star \: \: \: \green{ \overline{ \green{ \underline{ \blue{ \boxed{ \pink{ \frak{Total \: Surface \: Area = 2πr(h + r) }}}}}}}}$

Putting the values we get

• $\sf{T.S. A. = 2 \times \frac{22}{7} \times 5(7 + 5)}$

• $\sf{T.S. A. = 2 \times \frac{22}{7} \times5 \times 12}$

• $\sf T.S.A. = 377.142 \: {cm}^{2}$

Hence the total surface area is 377.14 cm²
