Question

a metal cuboid of diameter 22cm×15cm× 7.5cm.was melted and cast into a cylinder of height 14cm.what is its radius
..need asap​

Answer 1

Answer:

7.5 cm

Step-by-step explanation:

volume of the cuboid = 22 x 15 x 7.5

= 2475 cm³

now this volume will become the volume of the cylinder of height 14 cm. therefore

2475 = π x r² x h

r² = 56.273

r = 7.5 cm

therefore radius of the cylinder will be around 7.5cm

Answer 2

Answer:

Given a metal cuboid of diameter 22cm×15cm×7.5cm

the volume of cuboid is L×H×B

so here

22×15×7.5=2475 cm^2

then according to question the cuboid is melted and cast into a cylinder of height 14cm

the volume of cylinder is πr^2h

πr^2×14

the volume of cuboid is equal to the volume cylinder

so

22×15×7.5=22/7×r^2×14

so radius of cylinder=56.25 cm
