Question

R=3, H=7. find curved cylinder surface area, total surface area and volume of a cylinder​

Answer 1

volume=198

total surface area=1320/7

curved surface area=132

Step-by-step explanation:

vol= 22/7×

Answer 2

$\huge \color{lime}ANSWER :$

We have,

r=3 cm,h=7 cm

We know that the volume of the cylinder

V=πr² h

V= 22/7 ×3² ×7

V=22×9

V=198 cm³

We know that the curved surface area of the cylinder

Ac =2πrh

Ac =2× 22/7 ×3×7

Ac =22×6

Ac =132 cm²

We know that the total surface area of the cylinder

AT =2πr² +2πrh

AT =2× 22/7 ×3² +2× 22/7 ×3×7

AT =56.57+132

AT =188.57 cm²

Hence, this is the answer.
