Answer:
V ≈ 1847.26
Step-by-step explanation:
Circular Cone Formulas in terms of radius r and height h:
The volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
The base surface area of a cone (a circle):
B = πr2
The total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Therefore, the solution V = πr 2h / 3 = π·142·9/ 3 ≈ 1847.25648

Answer:
10/16
Step-by-step explanation:
Just multiply the denominator and the numerator by 2 and wha la you get 10/16 hope it helps!
Answer:
If you mean 5/8 ([tex]\frac{5}{8}[/tex]), then your answer would be 5 8 or 10/16 ([tex]\frac{10}{16}[/tex]).
10/16 simplified is actually 5/8!

Step-by-step explanation:
A right cone has radius 5 ft and slant height 9 ft. The radius and slant height are both multiplied by 1/2. Which of the following correctly describes the effect on the surface area?
Answer:
101.07ft^2
Step-by-step explanation:
Given data
radius= 5ft
h= 9ft
When the radius and height are both multiplied by 1/2
radius= 5/2ft = 2.5ft
height= 9/2 ft= 4.5ft
The expression for the surface area of the cone is
A=πr(r+√h^2+r^2)
Substiute
A= 3.142*2.5(2.5√4.5^2+2.5^2)
A= 7.855(2.5√20.25+6.25)
A= 7.855(2.5√26.5)
A= 7.855(2.5*5.147)
A=101.07 ft^2
Hence the surface area is 101.07ft^2
Answer:
The surface area is multiplied by 1/4.

Answer the question in the photo. What would be the area and what would be the cost?
Select the correct answer. Factor the expression. A. (7x − 4)(7x − 4) B. (4x − 7)(4x − 7) C. (7x + 4)(7x − 4) D. (4x + 7)(4x − 7)
Answer:
C. (7x + 4)(7x − 4)
Step-by-step explanation:
Given expression:
49x² - 16
Using difference of two squares:
A² - B² = (A + B)(A - B)
49x² - 16 = (7x)² - (4)²
= (7x + 4)(7x - 4)
C. (7x + 4)(7x − 4)
Check:
(7x + 4)(7x − 4)
Open parenthesis
= 49x² - 28x + 28x - 16
= 49x² - 16
Evaluate the expression. 5²

help please i really need it
i need help again lol-
Answer:
1.5
Step-by-step explanation:
Okay, so let's try this again, the median is the middle number, but the funny thing is, we have 8 numbers here, so we don't have a middle number. The closest we get is the middle of 1 and 2, which is 1.5.
Hope this helps:)
The base of a triangle is 5 units greater than the height, if its area is 18cm2, what is the quadratic equation that models the situation described and is used to find the height of the triangle?
base= 5+h
height= h
area= 1/2bh, so since our area us 18cm^2
therefore 18=1/2*b*h
18*2=(5+h)*h
36=5h+h^2
h^2+5h-36=0 ( for quadratic equation)
h^2+9h-4h-36=0
(h^2+9h)(-4h-36)=0
h(h+9)-4(h+9)=0
(h-4)(h+9)=0
h=4 or h= -9
Two angles that total 180 degrees are called
Answer:
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be.
Answer:
They are supplementary angles

I will give you the formula, you can do the calculations and I will confirm in a comment
Step-by-step explanation:
[tex]area = \pi {r}^{2} [/tex]
[tex]r = \frac{diamter}{2}[/tex]
[tex]area = \pi { \frac{d}{4} }^{2} [/tex]
[tex]circumstance = \pi d[/tex]
can someone please help me with this question?? (no links!!!)
Answer:
180ft
Step-by-step explanation:
By using the formula, we do Pi (3) x the radius which is 6² then x by the height, so, we do 3 x 6² x 5. 6² is 36. 3 x 36 = 108. Next, we do 5 x 108. This gives us 540. Now, we have to divide by 3. This makes our answer 180ft.
A map show a town with an area of 3.5 inches.If the map has a scale of 1 inch:4 miles,what is the actual area of the town?
Answer:
The actual area of the town is 14 miles.
Step-by-step explanation:
Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:
Scale: 1 inch:4 miles
map area: 3.5 inches
If the actual area is x, you can say that:
3.5:x=1:4
This would be:
[tex]\frac{3.5}{x}=\frac{1}{4}[/tex]
Now, you can solve for x:
x=(3.5*4)/1
x=14
According to this, the answer is that the actual area of the town is 14 miles.

What inequality symbol below makes the statement above true? 3.5_3/5
Answer:
3.5>3/5
Step-by-step explanation:
Jack's gross weekly pay is $498. He has $52 withheld from each paycheck for federal income
tax. In addition, Social Security, Medicare, state tax of 2.5 percent, and local tax of 1.25
percent are withheld from his paycheck. How much is withheld in Social Security, Medicare,
State, and Local taxes? Finally, what is his net pay?
Answer:
A. 56.78 B. 389.22
Step-by-step explanation:
A.Social security: 498x.062=30.88
medicare: 498x.0145=7.22
state tax: 498x.025=12.45
local tax: 498x.0125=6.23
total of above = 56.78
B. Total taxes above (56.78) + federal withheld (52) = total taxes 108.78
total pay 498 - total taxes 108.78 = 389.22

The perimeter of a square is 52 m. What is the area of the square?
The perimeter of a square is 52 m. What is the area of the square ?
Solution:-Perimeter of a square = 52 m
4 × side = 52
side = [tex] \frac{52}{4} [/tex]
side = 13
So, area of square = (side)² = (13)² = 169 sq m.
The area of the square is 169 sq m. [Answer]Answer:
A = 169 m²
Step-by-step explanation:
The sides (s) of a square are equal , then
s = perimeter ÷ 4 = 52 ÷ 4 = 13 m
The area (A) of a square is calculated as
A = s² = 13² = 169 m²
