Answer:
Area=7.071428571
Step-by-step explanation:
Before finding its area lets find its radius.
Given,
Diameter=3
Now,
Radius,r=D/2
r =3/2
r=1.5
Again,
Area of circle,A= pi*r*r
A =22/7*1.5*1.5
A=22/7*2.25
A=49.5/7
A=7.071428571 ans.

3.72 divided by 10^4 which of these shows and explains the correct location of the decimal point when the expression is evaluated?
A 0.0000372 because 4 zeros are placed in font of the number when you divide by 10 to the fourth power
B 0.000372 because the decimal point moves 4 places to the left when you divide by 10 to the fourth power
C 37,200 because the decimal point moves for places to the right when you divide by 10 to the fourth power
D 3,720,00 because 4 zeros are placed after the number when you divide by 10 to the fourth power
Answers
Answer:
B
Step-by-step explanation:
This is the answer because when you move the decimal point 4 places to the LEFT( moving left is for dividing while moving right will be for multiplying, also this only works for exponents of 10) it will equal to 0.000372.

Solving forr
r=(3V
4π)⅓=(3·802
4·π)⅓≈5.76362m
Answer:
r = 5.8 meters
Step-by-step explanation:
The volume formula is V = (4/3)(pi)(r^3), where r is the radius.
Solving for r, we get first 3V = (4pi)(r^3), so that r^3 = (3V)/(4pi)
or in this case, r^3 = 3(802 m^3) / (4pi) = 191.5 meters^3
Taking the cube root of both sides yields r = 5.8 meters

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
Answers
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Answer:
-0.58
Step-by-step explanation:
The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.
I hope this helps and please mark me as brainliest!
Answer:
-0,56
Step-by-step explanation:
As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6
So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.
Another way of putting this is you must add 0.02.
For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02
First notch: -0.6 + 0.02 = -0.58
Answer: Second notch: -0.58 + 0.02 = -0,56

To find the equation, you have to know the slope (5x) and the y intercept (25)
(Formula: y=mx+b) It says the input= x.
So plug 200 for x
5(200)+25=1025
The value of output for value of input of 200 is,
⇒ y = 1025
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The table shows the outputs for several inputs.
Now, We can find the expression for the table as;
Take two points are (0, 25) and (1, 30)
Hence, The equation is,
y - 25 = (30 - 25) / (1 - 0) (x - 0)
y - 25 = 5x
y = 5x + 25
Hence, The value of output for value of input of 200 is,
y = 5 × 200 + 25
y = 1000 + 25
y = 1025
Thus, The value of output for value of input of 200 is,
⇒ y = 1025

2. The border increases the length of each side by 1 foot
3. The width of the border is 6 inches (0.5 feet) because it adds on 1 foot in length to each side. Splitting it between the 2 borders for each side would make it 6 inches.
Answer:
1. 6 ft
2. 1 ft
3. 1/2 ft
Step-by-step explanation:
We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.
Area of a square = s² (where s is the side length)
If the finished quilt has an area of 36 ft² then the length of one side is:
⇒ s = √(36) = 6 ft
Side length of main design = 5 ft
Side length of finished quilt = 6 ft
6 - 5 = 1 ft
Therefore, the border increased the total length of each side by 1 ft
As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.
Therefore, the width of the border is 1/2 ft
**see attached diagram. Main design is shown in blue, border is shown in green**
