Find the volume of 20m, 5m, 18m
HACTEHA [7]

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula:<u><em> (volume of a rectangular pyramid)</em></u>

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

    \Longrightarrow \text{volume} \  =\  \frac{1}{3} \times 360\times 5

\Longrightarrow \  \text{volume} \  =\  600\  m^{3}

The volume of a cone with a radius of 7 cm is 147 cubic centimeters. Which expression can be used to find h, the height ofthe co
spayn [35]

The choices are not attached but we can solve the problem from the given information

Answer:

The expression can be used to find h is  h=\frac{3V}{\pi r^{2}}

The height of the cone is \frac{9}{\pi } cm

Step-by-step explanation:

The formula of the volume of the cone is V = \frac{1}{3} π r² h, where

  • r is the radius of its base
  • h is the height of it

Let us find the height of the cone from the formula of its volume

∵ V = \frac{1}{3} π r² h

- Multiply both sides by 3

∴ 3 V = π r² h

- Divide both sides by π r²

∴ \frac{3V}{\pi r^{2}}=h

- Switch the two sides

∴ h=\frac{3V}{\pi r^{2}}

The expression can be used to find h is  h=\frac{3V}{\pi r^{2}}

∵ The radius of the cone is 7 cm

∴ r = 7

∵ The volume of the cone is 147 cm³

∴ V = 147

- Substitute them in the expression of the height to find it

∵  h=\frac{3(147)}{\pi (7)^{2}}

∴ h = \frac{9}{\pi } cm

The height of the cone is \frac{9}{\pi } cm
