Hey!!
Since both are drawn or made from same quantity of material
Volume of cuboid = Volume if cylinder
l × b × h = π r^2h
22 × 1.5 × 7.5 = 22/7 × r^2 × 14
1.5 × 7.5 = r^2 × 2
11.25÷2 = r^2
√5.625 = r
r = 2.37

here the volume of the cuboid will be e
qual to the volume of the cylinder .
l × b× h = π r^2 h
22× 1.5 × 7.5 = 22 ÷ 7 × 14 × r ^ 2
r^2 = 1.5 × 1.5 × 2.5
r = √1.5 × 1.5 × 2.5
r = 1.5 √2.5
