1.John has a sink that is shaped like a half-sphere. The sink has a volume of 1072 in. One day, his sink
Vlad [161]

Answer:

\large\boxed{\large\boxed{85cups}}

Explanation:

<u>1. Volume of a cup</u>

The shape of the cup is a cylinder. The volume of a cylinder is:

       \text{Volume of a cylinder}=\pi \times (radius)^2\times height

The diameter fo the cup is half the diameter: 2in/2 = 1in.

Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:

         \text{Volume of the cup}=\pi \times (1in)^2\times 4in\approx 12.57in^3

<u>2. Volume of the sink:</u>

The volume of the sink is 1072in³ (note the units is in³ and not in).

<u>3. Divide the volume of the sink by the volume of the cup.</u>

This gives the number of cups that contain a volume equal to the volume of the sink:

          \dfrac{1072in^3}{12.57in^3}=85.3cups\approx 85cups

A shipping container is in the shape of a right rectangular prism with a length of 13
Lilit [14]

Answer:

371 pounds

Step-by-step explanation:

First you find how much space is in the container

length is 13

width is 15

height is 10

2 * (15 * 13 + 10 * 13 + 10 * 15)= 950

The total space in the container is 950

Then multiply it by 0.39 to find the weight

950 * 0.39 = 370.5

Round to the nearest pound

.5 rounded is rounded to a whole number

371 pounds
