A cylindrical well is 15 meters deep and has a diameter of 1.6 meters. Approximately how many cubic meters of soil were dug out

Lisa [10]

We can dig out the soil from the well equal to volume of well.

Height(h) of well is = 15 meters.

Diameter = 1.6 meters.

So radius(r) = $\frac{1.6}{2} = 0.8$ meter.

As well in cylindrical shapes.

So volume of well = $\pi r^2h$
                               = $\pi * (0.8)^2 * 15$
                                $= 9.6 * \pi$
In general $\pi = 3.14$

So volume of well is = $9.6 * 3.14$
   $= 30.144$ cubic meter.

So we can dig out 30.144 cubic meter soil from well.

Pablo buys a mattress set for 15% of the regular price and uses a coupon for 20% off the reduced price. If Pablo paid $1223.32 f

geniusboy [140]

Answer:

$1799

Step-by-step explanation:

We simply work backwards and write out an equation.

Lets call the initial price P.

First we have 15% off the initial price P which means that we are only paying 85% of the initial price: .85*P.

Next we use a coupon for 20% off the reduced price which means we only pay 80% of the reduced price: .80 * (.85 * P)

We know that the price paid was $1223.32, set that equal to .80 * (.85 * P)

and we find that P is $1799

Answer:

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

4x+11 +51 = 10x -10

Combine like terms

4x+62 = 10x -10

Subtract 4x from each side

4x+62-4x = 10x-10-4x

62 = 6x-10

Add 10 to each side

62+10 = 6x-10+10

72 = 6x

Divide by 6

72/6 = 6x/6

12 =x

We want to find angle D

<D =4x+11

= 4*12 +11

= 48+11

= 59
