A firework rocket consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of the cylindrical base of the rocket is 8 in and the height of the cylinder is 5 in, while the height of the cone is 3 in. Calculate the surface area of the rocket. Leave your answer in terms of π.
Answer:
188π in^2
Step-by-step explanation:
Surface area of the rocket = surface area of the cone + surface area of the cylinder
Surface area of a cone = πr(r+h^2+r^2)
r = 8/2 = 4 in
4π( 4 + 3^2 + 4^2) =
4π ( 4 + 9 + 16) = 116π in^2
Surface area of a cylinder = 2πrh+2πr^2
(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2
116 + 72 = 188π in^2

Answer:
8 x 1/6
Step-by-step explanation:
2 x 4/6 as a multiplication of a whole number and a unit fraction.
First off lets find 2 x 4/6
2 x 4/6 = 8 /6
Ok, now lets go back to the original equation.
2 x 4/6
divide 4/6 by 4 to get a unit fraction
A x 1/6
Divide 8/6 by 1/6 = 8
Or you can do A (previously known as 2) by 4 because we divide 4/6 by 4
A = 2x4 = 8
8 x 1/6 = 8/6
Correct

------Find the surface area of the figure, round your answer to the nearest hundredth if necessary <3
5.1 in
1 in
Answer:
[tex]\approx19.16[/tex]
Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, ([tex]\pi[/tex]) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Substitute,
[tex]a^2+(1)^2=(5.1)^2[/tex]
Simplify,
[tex]a^2+1=26.01[/tex]
Inverse operations,
[tex]a^2=25.01\\a\approx5[/tex]
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Substitute,
[tex]A=(\pi)(1)(1+\sqrt{5^2+1^2}})[/tex]
[tex]A=(\pi)(1+\sqrt{25+1})\\A=\pi(1+\sqrt{26})\\A\approx 19.16[/tex]

Melissa built a square pyramid out of sand. The base of the pyramid has a side length of 18 centimeters. The height of the pyramid is 26
centimeters.
What is the volume of the pyramid?
A. 624 cm3
B. 1,872 cm
C. 2, 808 cm
D. 4,212 cm
E. 8, 424 cm
Answer:
C. 2, 808 cm^3
Step-by-step explanation:
Given that
The base of the pyramid is 18 centimeters
And, the height of the pyramid is 26 centimeters
We need to find out the volume of the pyramid
As we know that
The volume of the pyramid is
= 1 ÷ 3 × base^2 × height
= 1 ÷3 × 18^2 × 26
= 2,808 centimeter^3
Hence, the correct option is c.

What is the value of x for this triangle.
Answer:
13
Step-by-step explanation:
you have to use Pythagorean Theorem which is
(a^2) + (b^2) = (c^2)
where a and be are the legs 45° from each other and c is the hypotenuse.
so just plug in the numbers
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
now square root both sides to get rid of the square on c
root(169) = root(c^2)
13 = c

Which is the solution set of this equation? |x – 6| = 15 A. {-9, 21} B. {-15, 15} C. {9, 21} D. {-9, -21} E. {-6, 6}
Answer:
A. -9, 21
Step-by-step explanation:
Use m.a.t.h.w.a.y and you will get the answer!
Answer:
A
Step-by-step explanation:
| x-6| = 15 , check if this is true for the given x values
for x= -9 we have | -9-6| = 15 true
for x= 21 we have | 21 -6| = 15 true
so A is a solution set
for x= -15 we have | -15-6| = 15 false
so B is not a solution set
for x= 9 we have | 9-6| = 15 false
so C is not a solution set
for x= -9 we have | -9-6| = 15 true
for x= -21 we have | -21-6| = 15 false
so D is not a solution set
for x= -6 we have | -6-6| = 15 false
so E is not a solution set
Im really struggling with this, i need A on this test please help me!

The least common denominator is 12
=======================================================
Explanation:
Your teacher wants you to list the multiples of each denominator.
The multiples of 3 are: 3, 6, 9, 12, 15The multiples of 4 are: 4, 8, 12, 16, 20The values in bold are what will go in the boxes in those first two rows.
The least common denominator is 12 because it is the smallest thing found in common in the two lists above. In other words, 12 is the LCM (least common multiple) of 3 and 4. Note how 3*4 = 12. This works because 3 and 4 do not have any common factors between them other than 1.
The LCD (least common denominator) is the LCM of the denominators. The LCD is useful for when you want to add or subtract fractions. The denominators must be the same for you be able to add or subtract them.
Solve this system of equations by using the elimination method. 2x - 2y = 2. 5x + 2y = 12 (2, [?])

In a class the ratio of boys to girls is 4:3 30% of the boys are left handed.
What fraction of all the people in the class are left handed boys?
6/35 fraction of people in the class are left handed
What is ratio and proportion?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
Let the total no. of students in a class be x
then no. of boys in the class be 4x/7
no.of girls in the class be 3x/7
left handed boys =30%of 4x/7
= 3/10x 4x/7
=6x/35
Therefore, 6/35 fraction of people in the class are left handed
