Question

Find the Curved surface area whose radius is 7 cm and hieght is 10 cm

Answer 1

Radius(r)= 7

Height (h)=10

so we know that

CSA of cylinder is 2πrh

CSA of cylinder= 2×22/7×7×10

=2×22×10

=440cm²

Therefore CSA of cylinder is 440cm²

Hope it's help you

Answer 2

[[ Language: Maths ]]

Answer:

440 cm²

Given:

▪︎radius = 7cm

▪︎height = 10cm

To find:

▪︎Curved Surface Area of the Cylinder.

$= \: 2 \: \pi\: r \: h$

Step-by-step:

• 2 × 22÷7 × 7 × 10
• = 2 × 22 × 10
• = 440

Hope it helps,

thanks!
