Question

Find the height of a cylinder whose volume is 1.54 m³ and diameter of base is 140 cm​

Answer 1

1 m

Explanation:

diameter of base = 140 cm

so, radius = 70 cm

`height \: of \: cylinder = (volume )/(area \: of \: base) \\ \\ h = (V_(cylinder))/(\pi r^2) \\ \\ = (1.54 * 1000000)/(3.14*(70)^2) \\ \\ = (1540000)/(15386) \\ \\ = 100.09 \: cm\\ \\ h \approx 1 \: m`
