Find the volume of the cylinder. a) 2020 cm3 b) 2156 cm3 c) 1234cm3 d) none of these​

Answer 1

Answer:

26 , A

27 , C

28 , B

29 , A

30 , D

Step-by-step explanation:

GIVEN, hight of cylinder = 7cm

radius of cylinder = 15cm

26 , side of cube is equal to half of radius i.e. l = r/2,

$l = \frac{14}{2} = 7cm \\ this \: is the \: side \: of \: cube(all \: sides \: of \: any \: cube \: is \: equal)$
