Question

Find the height of a cylinder with radius of 3.5 cm and volume is 1540cm

Answer 1

Step-by-step explanation:

$volume = \pi \: r {}^{2}h$

$\frac{22}{7} \times (3.5) {}^{2} \times h$

$\frac{22}{7} \times 12.25 \times h = 1540$

$22 \times 1.75h = 1540 \\ 38.5h = 1540 \\ h = 40cm.$

Answer 2

$volume\ of\ cylinder = \pi r^2h = 1540\ cm^3\\\\radius = 3.5 cm\\\\1540 = \frac{22}{7} * 3.5*3.5 * h\\\\1540 = 38.5 * h\\\\1540 / 38.5 = h\\\\h = 40 cm\\\\hope \ it \ helps \ !!$
