Question

The total surface area of a cylinder with circular base of
radius 7 cm and height 10 cm is
​

Answer 1

Answer:

748m²

Step-by-step explanation:

2×22/7×7(7+10)

44×17

748m²

Answer 2

Given :

• A cylinder of radius 7cm and height 10cm.

To find :

• T. S. A. (Total surface area) of the cylinder.

Solution :

Total surface area of a cylinder is given by :

→ 2πr(r + h)

• Taking ‘π’ as $\sf \dfrac{22}{7}$
• r (radius) = 7cm.
• h (height) = 10cm.

So,

T. S. A. of the cylinder will be :

$\to \sf 2 \times \dfrac{22}{7} \times 7(7 + 10)$

$\to \sf 2 \times 22(17)$

$\to \sf 44(17)$

$\to \sf 748m^2$

∴ Total surface area of the cylinder is 748cm²
