Answer 1

Answer : c) 2816 cm cube

Step by step explanation:

Formula of Volume of Cylinder = πr^2h

=> 22/7 x 8 x 8 x 14

=> 2816cm^3

Answer 2

Answer:

Step-by-step explanation:

Given :

Volume of the cylinder is 448π cm³,

height of the cylinder is 7 cm.

Let the radius be r cm.

We know that,

Volume of cylinder = πr²h

=> 448π = πr²h

=>  = r² × 7

=> 448 = r² × 7

=>  = r²

=> 64 = r²

=>  =r

=> 8 = r

Therefore,

the radius of the cylinder is 8 cm.

Lateral surface area and total surface area of the cylinder.  

= 2πrh

= 2 ×  × 8 × 7

= 352 cm²

= 2πr(r + h)

 2 ×  × 8 ( 8 + 7)

= 754.28 cm²
