The truck's tank is a stainless steel cylinder. Find the surface area of the tank. Round your answer to the nearest hundredth.
Feliz [49]

Answer:

Area of the truck tank is 1356.48ft^2

Step-by-step explanation:

It is given height of the cylinder h = 50 ft

Radius of cylinder is r = 4 ft

Surface area of the cylinder is equal to

A=2\pi rh+2\pi r^2

Now putting the value of r and h

A=2\times 3.14\times  4\times 50+2\times 3.14\times  4^2

=1356.48ft^2

Therefore area of the truck tank is 1356.48ft^2

1) The cost of constructing a path 5 m broad inside the boundary of a square lawn at Rs 36.25 per sq. metre is Rs 90625. What is
Svetach [21]

Let , side lawn is a.

Area of boundary is :

A=4\times5\times a\\\\A=20a\ m^2

Now, total cost is given by :

T=20a\times 36.25\\\\90625=725a\\\\a=125\ m

Area left is :

A'=a^2-20a\\\\A'=125^2-20\times 125\ m^2\\\\A'=13125\ m^2

Price to empty space with turfs is :

P=A'\times 20\\\\P=13125\times 20\\\\P=262500

Therefore, the cost of covering the empty space with turfs at the rate of Rs 20 per sq. metre is Rs 262500.

Hence, this is the required solution.

Figure a is a scale image of figure b. what is the value of x? please answer asap!
emmainna [20.7K]

<em>Greetings from Brasil...</em>

According to the statement, one figure is scaled in relation to another, so we can apply similarity to polygons.....

So

BIG/small = BIG/small

or

small/BIG = small/BIG

12.5/10 = X/16

OR

10/12.5 = 16/X

12.5/10 = X/16

10X = 12.5 · 16

X = 200/10

<h3>X = 20</h3>
