Question

the volume of a 1 m long circular Island road is 2450 cm cube find its diameter

Answer 1

$\pi \times {100}^{2} \times x = 2450$
3.14×10000×x=2450
31400x=2450
$x = \frac{2450}{31400} |$
0.078025477707006cm

Answer 2

first here discussion about circular road

circular volume=2450cm³

4/3πr³=2450

r³= 2450×3/4π

r³=7350×7/(22×4)

r³=584.66

r=8.36cm....answer
