Answer:

11,880π in^3

Step-by-step explanation:

The volume of a cylinder = π r^2 h

Large Cylinder V = π * 15^2*40 =  9,000π   in^3

Small Cylinder V = π * 12^2 * (60-40) =  2880π in^3

Adding: the total volume of the model = 11,880π in^3

The number of dimes in the bag can be represented by x. The number of quarters is 6 more than twice the number of dimes. There a
Ilia_Sergeevich [38]

Answer:

The number of dimes  is represented by x = 90

Step-by-step explanation:

Given that:

The number of dimes  is represented by x

Number of quarters = 6  + 2x

Total number of coins in the bag = 276

To find x, we have:

x + 6 + 2x = 276

3x + 6 = 276

3x = 276 - 6

3x = 270

x = 270/3

x = 90

The size of a typical city park is about 5 acres, or 217,800 square feet. If a developer plans to
pshichka [43]

Using the percentage concept, it is found that 95.4% of the park will be used for other activities.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

P = \frac{a}{b} \times 100\%

In this problem, there will be two courts of 5,000 square feet each, totaling 10,000 square feet. The remainder 207,800 square feet will be used for other activities, hence the percentage is given by:

P = \frac{207,800}{217,800} \times 100\% = 95.4\%

95.4% of the park will be used for other activities.

Before you can make a pie chart you need to figure out how much of the circle belongs to each category. Suppose that you earned
svetoff [14.1K]

Answer:

missions-24

recreation-108

savings-144

school supplies-48

tithe-36

Step-by-step explanation:

so first convert all the given costs to cents by multiplying each amount with 100 then add all of them to get the total as 600

in a pie chart we know that it's a circle and all angles within the circle must add up to 360 so to get an angle for a certain cost that will represent it in the chart you have to take that cost over the total to get the fraction of the circle it will occupy multiplied by 360 to get it in degrees or which portion of 360 will it occupy hence

60/600×360=36
