The radius of a circle is 18 in what is the area and circumference ​
Inessa05 [86]

Answer:

324 pi .  and 36 pi

Step-by-step explanation:

Area is pi r squared, so 18x18 is 324, times pi which is 324 pi

Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi

The cost, C, in millions of dollars of producing T million tons of steel is modeled by the equation C = 220T + 1890.
kobusy [5.1K]

C = 220T + 1890.

Solve the equation for T.

220T = C - 1890

T = C/220 - 8.6

The steel produced is expected to be sold at a price of $310 per ton.

310 $/ton is a rate or slope. Write a linear equation where x is tons of steel produced and y is selling price of the steel.

y = 310x

Write and solve an equation to find the amount of steel produced if the selling price is equal to the cost of production.

* Here, note that the cost of production and tons of steel in the first equation is in the millions.  The equation we just wrote for the selling price was in x tons of steel. This only matters in regards to the units you specify because; million/million = 1

The unit multiplier of all variables must be specified as same. Either everything is in millions or not.

Here, I'll leave everything in millions, change x (tons of steel) to T (mill tons steel) and "y" to "S" in million dollars selling price.

S = 310T

Set equal to Cost equation.

220T + 1980 = 310T

Solve for T, million tons of steel produced.

1980 = 310T - 220T

1980 = 90T

T = 1980/90

T = 22 million tons steel produced

A child’s wading pool has a diameter of 5 feet and a height of 2 feet. How much water would it take to fill the pool?
Svetradugi [14.3K]

Answer:

12.5π or ≈39.27

Step-by-step explanation:

The formula for finding the volume is V=πr^2*d (where h is the height and r is  the radius).

Plug in the values: V=π(2.5)^2*2 (Diameter=2*Radius)

Solve: V=6.25π*2

V=12.5π

V≈39.27

Find the value of x if a,b, and c are collinear points an b is between a and c
MakcuM [25]
\sf Hello!

• \sf AB = x + 6
• \sf BC = 3x - 5
• \sf AC = 36 - x

\sf We're \:given\: that \:A,\: B\: and \:C \:are \:Collinear\: points

\sf Then,

\sf AB + BC = AC

⇒ \sf x + 6 + 3x - 5 = 36 - x

⇒ \sf x + 3x + 6 - 5 = 36 - x

⇒ \sf 4x + 1 = 36 - x

⇒ \sf 4x + x = 36 - 1

⇒ \sf 5x = 35

⇒ \sf x = \dfrac{\sf 35}{\sf 5}

⇒ \boxed{\sf x = 7}

\sf Hence,

\sf The\: value\: of\: x\: is\: D.\: 7
