The world's tallest building is the Burj Khalifa in Dubai at 828 m tall. The CN Tower in Toronto is 553 m tall. Ryan wants to co

mpare the Burj Khalifa and the CN Tower by creating rectangular prism models on a 10 cm by 10 cm square base. He has decided to represent the Burj Khalifa with a rectangular prism that has a height of 40 cm. What is the volume of each rectangular prism? Round your answer to the nearest cubic centimetre.

Answer:

Volume of Burj Khalifa Prism = 4000 cm^2

Volume of CN Tower Prism = 2671 cm^2

Step-by-step explanation:

Given

Height of Burj Khalifa = 828 m

Height of CN Tower in Toronto = 553 m

Base of rectangular prism is a square with sides <em>10 cm </em>\times<em> 10 cm</em>.

Height of Burj Khalifa prism = 40 cm

828 m is represented as 40 cm

\Rightarrow 553 m is represented as \frac{40}{828 } \times 553 = 26.71\ cm

So, height of rectangular prism of CN Tower = 26.71 cm

Volume of a Prism is given by the Formula:

V=Area\ of\ Base \times Height

Base is a square, so Area of base = Side^2

Volume of Burj Khalifa Prism:

V_B=10^2 \times 40 = 4000\ cm^2

Volume of CN Tower Prism:

V_C=10^2 \times 26.71 = 2671\ cm^2

So, the answer is:

Volume of Burj Khalifa Prism = <em>4000</em> cm^2

Volume of CN Tower Prism = <em>2671 </em>cm^2

A cone with radius 2 and height 9 has its radius tripled. How many times greater is the volume of the larger cone than the small
SpyIntel [72]

Answer:

When increasing the radius 3 times the volume increases 9 times and when it is reduced to a third the volume decreases 9 times

Step-by-step explanation:

We have that the formula for the volume of a cone is:

Vc = pi * (r ^ 2) * h

We first calculate the original volume, where the radius is 2 and the height is 9, replacing:

Vc = 3.14 * (2 ^ 2) * 9

Vc = 113.04

Now if the radius is tripled it would be: 2 * 3 = 6, the radius would be 6, replacing:

Vc = 3.14 * (6 ^ 2) * 9

Vc = 1017.36

If we compare:

1017.36 / 113.04 = 9

This means that when the radius is tripled, the volume increases 9 times.

When if re reduces to a third the radius would be: 2/3, replacing:

Vc = 3.14 * ((2/3) ^ 2) * 9

Vc = 12.56

113.04 / 12.56 = 9

Which means that by reducing it to a third the volume becomes 9 times smaller.

Suppose that a cyclist began a 476
mojhsa [17]
Well, we know the cyclist left the western part going eastwards, at the same time the car left the eastern part going westwards

the distance between them is 476 miles, and they met 8.5hrs later

let's say after 8.5hrs, the cyclist has travelled "d" miles, whilst the car has travelled the slack, or 476-d, in the same 8.5hrs

we know the rate of the car is faster... so if the cyclist rate is say "r", then the car's rate is r+33.2

thus    \bf \begin{array}{lccclll}&#10;&distance&rate&time\\&#10;&-----&-----&-----\\&#10;\textit{eastbound cyclist}&d&r&8.5\\&#10;\textit{westbound car}&476-d&r+33.2&8.5&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;\begin{cases}&#10;\boxed{d}=8.5r\\\\&#10;476-d=(r+33.2)8.5\\&#10;----------\\&#10;476-\boxed{8.5r}=(r+33.2)8.5&#10;\end{cases}

solve for "r", to see how fast the cyclist was going

what about the car? well, the car's rate is r + 33.2
