Answer 1

Answer:

hey mate here is your answer....

Explanation:

▶️ The height of cylinder is a 80 cm and the diameter of its base is 7 cm .The whole surface area of the cylinder?

________________________________________________________________-----_________________

➡️The length/height of cylinder = 80 cm

➡️ Radius = 7/2

☑️Total surface area of the cylinder = 2πr ( r + h)

$\: \: \: | 2 \times \frac{22}{7} \times \frac{7}{2} ( \frac{7}{2} \times 80) \: cm.sq$

$22 \times \frac{167}{2} \: cm.sq$

11 x 167 cm²

1837cm²

☑️ So the total surface area of the cylinder is 1837cm²

Hope it helps!☺️
