Question

The radius of right circular cylinder is 7cm and height is 10cm. What will be its curved surface area?​

Answer 1

Answer:

Given -

• radius = 7 cm
• height = 10 cm

• A=2πrh+2πr2=2·π·7·10+2·π·72
• =747.69905cm²

• Curved Surface area = 747.7cm²

Answer 2

Answer:

Curved surface Area = 440$cm^{2}$

Step-by-step explanation:

According to the information provided in the question it is given as

Radius = 7 cm

Height = 10 cm

We need to find the curved surface area

So understand the curved surface area of cylinder

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases.

Apply the formula of curved surface area

A=2πr h

[tex]A =2\times \frac{22}{7} \times 7 \times 10\\ A = 2\times 22\times 10\\ A =440cm^{2} [/tex]

Curved Surface area = 440$cm^{2}$
