1. Answer:

   20.95 [tex]cm^{3}[/tex]

   Step-by-step explanation:

   Volume of cone = [tex]\frac{1}{3}[/tex] π [tex]r^{2} h[/tex]

   Given : r = 2cm , h = 5cm

   ⇒ Volume of cone = [tex]\frac{1}{3} (\frac{22}{7} )(2^{2} )(5)[/tex] = [tex]\frac{440}{21}[/tex] ≈ 20.95 (approx.)

2. Answer:

   20.95cm³

   Step-by-step explanation:

   Height of cone=5cm

   Radius of cone=2cm

   Volume of cone=1/3πr²h

   =1/3×22/7×2²×5

   =22/21×4×5

   =22/21×20

   =440/21

   =20.95cm³. (approx)
