Which expression represents the volume of the pyramid? One-fifth(5.2)h cm3 StartFraction 1 Over 5 h EndFraction(5.2)h cm3 One-th
anyanavicka [17]

Answer:

1/3(5.2)h cm³

Step-by-step explanation:

A solid right pyramid has a regular hexagonal base with an area of 5.2 cm2 and a height of h cm. Which expression represents the volume of the pyramid?

One-fifth(5.2)h cm3 StartFraction 1 Over 5 h EndFraction(5.2)h cm3

One-third(5.2)h cm3 StartFraction 1 Over 3 h EndFraction(5.2)h cm3

Volume of the pyramid = 1/3 × area × height

Area = 5.2 cm²

Height = h cm

Volume of the pyramid = 1/3 × 5.2 cm² × h cm

= 1/3(5.2)h cm³

A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full?
dusya [7]
<span> By definition, the volume of a cone is given by:
</span> V = (1/3)*( \pi)*(r^2)*(h)&#10;
<span> Where,
 r: radius of the circular base of the cone.
 h: cone height
 The cone radius is given by:
</span> r = d / 2 &#10;
<span> Where,
 d: diameter of the circular base.
 Substituting values we have:
</span> r = 6/2 &#10;&#10;r = 3 cm<span>
 Then, the volume will be:
</span> V = (1/3) * (3.14) * (3 ^ 2) * (10) &#10;&#10;V = 94.2 cm ^ 3<span>
 Answer:
 The volume of the cone is given by:
</span> V = 94.2 cm ^ 3<span>
</span>
