Question

the radius of the base of a closed cylinder is 7cm and height is 10 cm find the total surface area​

Answer 1

Answer:

given that,

radius= 7cm

height = 10cm

TSA=

$2\pi \: r(r + h)$

2 x 22/7 x 7(7+10)

14 x 22/7 (17)

2 x 22 (17)

44(17)

748

there fore, Total Surface Area of cylinder is 748cm²
