Sagot :

Let's see

  • V=πr²h
  • π(8)²h=1280π
  • 64h=1280
  • h=1280/64
  • h=20cm

Answer:

A.  20 cm

Step-by-step explanation:

Volume of a cylinder

[tex]\textsf{V}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

Given:

  • [tex]\sf V=1280 \pi \: cm^3[/tex]
  • [tex]\sf r=8\:cm[/tex]

Substituting the given values into the formula and solving for h:

[tex]\begin{aligned}\implies \sf 1280 \pi & =\sf \pi 8^2h\\\\\sf 1280 \pi & = \sf 64 \pi h\\\\\sf h & = \sf \dfrac{1280 \pi}{64 \pi}\\\\ \sf h & = \sf 20\:cm\end{aligned}[/tex]
