Answer:

Surface area of  Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)

Step-by-step explanation:

Given:

Radius of the Earth = 3,960 miles

Find:

Surface area of  Torrid Zone (cylinder shape) = ?

Computation:

We know that, distance between two tropics is 3,250 miles.

So, Height = 3,250 miles

Surface\ area\ of\ Torrid\ Zone=2\pi rh\\\\Surface\ area\ of\ Torrid\ Zone=2\times \frac{22}{7}\times 3,960 \times 3,250\\\\Surface\ area\ of\ Torrid\ Zone=80,897,142.9

Surface area of  Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)

Answer:

Can 1 will contain more stew

Step-by-step explanation:

<h2>Can -1 </h2>

diameter= 8

radius=d/2=4

height=4

therefore volume= \pi r2 h= 201.06

<h2>Can-2</h2>

Diameter= 6

radius=d/2=3

height= 7

therefore volume= \pi r2 h= 197.92

A washer and a dryer cost $857 combined. The washer costs $93 less than the dryer. What is the cost of the dryer?
Lelechka [254]

Answer:

Dryer cost $475;  Washer cost $382

Step-by-step explanation:

For this problem, we will simply set up a system of equations to find the value of each the washer (variable x) and the dryer (variable y).

We are given the washer and dryer cost $857 together.

x + y = 857

We are also given that the washer cost $93 less than the dryer.

x = y - 93

So to find the cost of the dryer, we simply need to find the value of y.

x + y = 857

x = y - 93

( y - 93 ) + y = 857

2y - 93 = 857

2y = 950

y = 475

So now we have the value of the dry to be $475.  We can check this by simply plugging in the value and see if it makes sense.

x + y = 857

x + 475 = 857

x = 382

And check this value:

x = y - 93

382 ?= 475 - 93

382 == 382

Therefore, we have found the values of both the washer and the dryer.

Cheers.
