Use a net of the square pyramid, if necessary, to find the surface area of the pyramid.

Answers

Answer:

160

Step-by-step explanation:

You take the area of one of the triangles, which is 24, multiply that by 4. You get 96. You then add 64, the area of the square base, and end up with 160.

Answer:

160 units squared

Step-by-step explanation:

First we need to find the surface area of one of the triangles;

(8*6*0.5)

24

Next, we find the surface area of all of the triangles;

(24*4)

96

The next step is to find the surface area of the square;

(8*8)

64

The last step is to fins the surface area of the whole thing.

(96+64)

160

The surface area of the pyramid is going to be 160 units squared

Answers

Answer:

263.76

Step-by-step explanation:

It is 7 times 12 times 3.14. Then you round your answer

The formula for the volume of a cylinder is V=πr^2h. Which is volume equals pie * radius squared * height. pie = 3.14. radius is diameter/2, 3.5 in this case, then squared which is 3.5 * 3.5. And the height is 12. You take 3.14, 3.5^2, and 12 then multiply each term. So your substituted equation would be V=3.14(3.5^2)12.

This is how it would go:

V=3.14(3.5^2)12.
3.5^2 = 12.25.
- just squared 3.5, that equals 12.25

V=3.14(12.25)12
3.14 * 12.25 = 38.465
- pie times 12.25 equals 38.465

V=38.465(12)
38.465 * 12 = 461.58
- 38.465 * 12 = 461.58

V=461.58
- Your answer is 461.58 centimeters!!

There 18 students who play trumpet in the school band. The number of trumpet players is 2 more than 1/4 of the entire band. How many students are in the band?

Answers


18 students = trumpet
18-2 = 1/4 of band =16 people = 1/4 of band
so 16/4 = 64
18-2=16 and you just multiply 16 by 4.

Answer: 4

Step-by-step explanation: Since the total number of games played in the graph is 12, if you half that and get six, you half the total number of wins as well and get 4. :]

Answer:

B. 4

Step-by-step explanation:

First we need to find out the total amount of games played. Since there are no variables, we can just simply add up the values under "number of games".

Doing so will get us 12. Now lets convert each out come into a fraction.

Wins - 8/12

Loses - 2/12

Ties - 2/12

Once we have them in fractions we need to convert them to decimals then to percents. To do so we just need to divide the numerator by the denominator.

8/12 = 0.66666666

2/12 = 0.16666666

2/12 = 0.16666666

Next multiply each decimal by 100 to get the percent.

0.66666666*100 = 66.666666%

0.16666666*100 = 16.666666%

0.16666666*100 = 16.666666%

Finally you need to take the total amount of games, and divide it by each percent to find the amount of games won, lost and tied

The answer to this is 100

Answer:

its 100

Step-by-step explanation:

well since its a parallel line, 7 and 3 are corresponding and that makes 3 also 80. buh then 3 is also adjacent to 2 and that makes it also 80 and since 2 is on the same line as 1 and an angle on a straight line is 180, it automatically makes 1 an angle of 100 as 180 - 80 should give u 100.
