Question

if the radius of the base of a cylinder is 7cm and the length is 10 cm what is its curved surface area​

Answer 1

Answer:

curved surface area = 747.69905cm²

Step-by-step explanation:

A=2πrh+2πr2

=2·π·7·10+2·π·72

= 747.69905cm²

Answer 2

Given : radius of the base of a cylinder is 7 cm and the length is 10 cm,

To Find : curved surface area

1️⃣ 70 cm

2️⃣ 440 sqcm

3️⃣ 440 cubic cm

4️⃣ 700 sqcm​

Solution:

curved surface area   of cylinder = 2πrh

r = 7 cm

h = 10 cm

π = 11/7

=> CSA = 2(22/7)  7 * 10

= 2 * 22 * 10

= 440  cm²

curved surface area   is 440 cm²
