some body have asked this question I have forgotten the name the question is: the circumference of a circle is 36π cm what is the radius of a circle if any body finds it then please answer him or her
The formula for the area of a circle is given by A = πr², where r is the radius of the circle.
Since we know that area A = 36π, we can substitute into the formula for area A and get:
36π= πr²
Now, dividing both sides by π in order to begin isolating r on one side of the equation, we get:
(36π)/π = (πr²)/π
36(π/π) = (π/π)r²
36(1) = (1)r²
36 = r²
r² = 36 (since equality is symmetric, i.e., if a = b, than b =a)
Now, taking the square root of both sides, we have:
√(r²) = ±√(36)
r = √(36) (since a distance cannot be physically negative, then we have to use the positive square root)
r = 6 (since (6)(6) = 36)
CHECK:
A = 36π
36π= π(6²)
36π = π(36)
36π = 36π
Therefore, r = 6 is indeed the radius of the circle with an area of 36π.
Answer:
The radius of the circle is 6.
Explanation:
Take the square root of 36.

B. The y-intercept of Function A is 1 unit less than the y-intercept of Function B.
C. The y-intercept of Function A is 1 unit greater than the y-intercept of Function B.
D. The y-intercept of Function A is 2 units greater than the y-intercept of Function B.
The y-intercept of Function A is 1 unit greater than the y-intercept of Function B. Then the correct option is C.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,

The function A is passing through (0, 1), then the equation of the line will be
1 = 0m + c
c = 1
Then the equation of the function A will be y = mx + 1.
From, the graph, it is clear that the y-intercept of Function A is 1 unit greater than the y-intercept of Function B.
Then the correct option is C.

cross one by one on both sides
3, 5, 7,
5
#6. 1, 3, 4, 4, 6, 6
3,4,4,6
4,4
4 (because in the middle of 4 and 4 well is 4) (if you had 5 and 6 left it would be 5.5)
The mode is the # that appear the most often in the set of data.
#5. there is no more because there is one of each # there is none that has 2 or more (N/A)
#6. 1,3, 4, 4, 6, 6
the mode is 4 and 6
because those #'s have 2 or more and they are both at 2 so they are both the mode
The cone has a base diameter of 20cm and a slant height of 25 cm.
A circle is drawn around the surface of the cone at a slant height of 10cm above the base.
The curved surface of the cone above the circle is painted grey.
Work out the area of the curved surface of the cone that is not painted grey,
Give your answer as a multiple of
You must show all your working.
Answer:
The area of the cone not painted is approximately 196.35 cm²
Step-by-step explanation:
The question relates to similar shapes;
We have;
The base diameter of the cone, D₁ = 20 cm
The slant height of the cone, l₁ = 25 cm
The height at which the circle is drawn, 10 cm above the base, we have; l₂ = 25 cm - 10 cm = 15 cm
Let 'x' represent the diameter of the circle formed by the drawn circle, we have;
By similar triangles, we get;
D₁/l₁ = x/l₂
x = l₂ × D₁/l₁
20/25 = x/15
x = (20/25) × 15 = 12
The curved surface area of the cone, A = π·r·l
The area of the curved surface of the entire cone, A₁ = π·r₁·l₁
r₁ = D₁/2
Therefore, we get, A₁ = π × 20/2 × 25 = 250·π
A₂ = π × 15/2 × 25 = 187.5·π
The area of the cone not painted, A = A₁ - A₂
∴ A = 250·π - 187.5·π = 62.5·π
The area of the cone not painted, A = 62.5·π ≈ 196.35
The area of the cone not painted ≈ 196.35 cm²

Answer:
32
Step-by-step explanation:
formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]
where b = base length and h = height
The triangle shown has the following the dimensions
base length = 2 + 6 = 8m
height = 8m
Using these dimensions we plug in the values into the formula
[tex]A=\frac{8*8}{2} \\8*8=64\\\frac{64}{2} =32[/tex]

4571
Answer: $3,581
Step-by-step explanation:
As she plans to save from her net income, we have to find the net income first:
= Net income - Federal taxes - Social and Medicare taxes
= 33,000 - (33,000 * 20%) - (33,000 * 7.65%)
= $23,875.50
The savings will be:
= Net income * Savings percentage
= 23,875.50 * 15%
= $3,581.325
= $3,581

An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system. How long will it take until there is only 25 mg
of ibuprofen left in the person's system? Show all work and round your answer to
three decimal places.
Answer:
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Step-by-step explanation:
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system
This means that in 2 hours time
400- 201.6= 198.4 mg was used up.
We need only 25 mg in the system
so 400- 25= 375 mg time is needed
time mg
2 hour 198.4
x 375
Using the cross product rule
x= 375*2/198.4
x= 3.780 hrs
Which means 3 hours and (0.78* 60)= 46.8 minutes.
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

This is a quadratic function
write it in the form [tex]a(x-h)^2+k[/tex]
h and k is the vertex, meaning the coordinate that is lowest or highest point depending on where the function is...pointing. You can see that the function is point up, so h is the x coordinate is at the bottom. the vertex coordinate is (9, -4), im sure you know why. In the formula, h means the x and k is the y. So that means that the h is 9 and k is -4.
now the think will be [tex]a(x-9)^2-4\\[/tex]
now you find a by plugging one of the point, you can take the point (12, 4)
[tex]a(12-9)^2-4=4\\9a=8\\8/9=a\\[/tex]
so the equation
[tex]8/9 (x-9)^2 -4[/tex]
