Let 'r' be the radius of the base of a right circular cylinder.
And height given is 42 cm.
↪ Circumference of base = 88 cm
2 π r = 88
2 × 22 / 7 × r = 88
r = ( 88 × 7 ) / ( 22 × 2 )
r = 2 × 7
r = 14 cm
↪ Now,
= π r² h
= 22 / 7 × ( 14 )² × 42
= 22 / 7 × 196 × 42
= 22 × 196 × 6
= 25,88 cm³
Therefore, the volume of right circular cylinder is 25,88 cm³

Step-by-step explanation:
Let 'r' be the radius of the base of a right circular cylinder.
And height given is 42 cm.
↪ Circumference of base = 88 cm
2 π r = 88
2 × 22 / 7 × r = 88
r = ( 88 × 7 ) / ( 22 × 2 )
r = 2 × 7
r = 14 cm
↪ Now, volume of cylinder
= π r² h
= 22 / 7 × ( 14 )² × 42
= 22 / 7 × 196 × 42
= 22 × 196 × 6
= 25,88 cm³
Therefore, the volume of right circular cylinder is 25,88 cm³
