Question

find the curved surface area of cylinder, whoes radius is 7cm and height is 10cm.

Answer 1

Given:

• radius of the cylinder, r = 7 cm
• height of the cylinder, h = 10 cm

We know,

Curved Surface Area of a Cylinder = 2πrh

$</p><p></p><p>\rightarrow \quad 2 \times \pi \times r \times h \\ \\</p><p></p><p>\rightarrow \quad 2 \times \frac{22}{7} \times 7 \times 10 \\ \\</p><p></p><p>\rightarrow \quad 2 \times \frac{22}{\cancel{7}} \times \cancel{7} \times 10 \\ \\</p><p></p><p>\rightarrow \quad 2 \times 22 \times 10</p><p></p><p>\Rightarrow \quad 440 </p><p></p><p>$

Answer : 440 cm²

Answer 2

Step-by-step explanation:

radius is 7cm

height is 10cm

curved surface area of cyclinder is 2πrh

2*22/7*7*10

440cm2
