Q.
A circle has a radius of 21 cm. Then determine the area!
EASY
Hello there! :-)
The formula for finding the area of a circle is
[tex]A=\pi r^{2}[/tex]Notice that only the radius is squared.
We are given the radius of the circle: 21 cm.
We plug the value of r into the formula:
A=π(21)²A=π(441)A=1,385 cmHope this helps. Use the comment section to clarify your doubts.

Good luck.
Answer:
A=1.386 cm²
Step-by-step explanation:
[tex]\sf\bf A = \pi \times r \times r[/tex]
[tex]\sf\bf = \frac{22}{7} \times 21 \times 21[/tex]
[tex]\sf\bf = \frac{22}{\cancel{7}} \times \cancel{21} \times 21[/tex]
[tex]\sf\bf = 22 \times 3 \times 21[/tex]
[tex]\sf\bf = 66 \times 21[/tex]
[tex]\sf\bf = 1.386 \: {cm}^{2}[/tex]
An open-top box is to be constructed from a sheet of tin that measures 36 inches by 20 inches by cutting out squares from each corner as shown and then folding up the sides. Let V(x) denote the volume of the resulting box.
Answer:
[tex]V(x)=4x^3-112x^2+720x[/tex]
Step-by-step explanation:
[tex](36-2x)(20-2x)x[/tex]
[tex](720-72x-40x+4x^2)x[/tex]
[tex](4x^2-112x+720)x[/tex]
[tex]4x^3-112x^2+720x[/tex]
Therefore, the resulting volume would be [tex]V(x)=4x^3-112x^2+720x[/tex]

please help !! question is shown below in the picture
Answer:
C
Step-by-step explanation:
Given x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 20 , y = 10 then
10 = 20k ( divide both sides by 20 )
[tex]\frac{10}{20}[/tex] = [tex]\frac{1}{2}[/tex] = k
y = [tex]\frac{1}{2}[/tex] x ← equation of variation → C

If y varies directly with x, determine an equation for the given direct variation. For this question, find the value of the given variable.
Find y when x = 10 if y = 8 when x = 20.
Answer:
y=K*x equation
k=constant of variation
y= 4 when x = 10
Step-by-step explanation:
8=k*20
divide both sides by 20 to solve for k
2/5=k
y=2/5 *10
y= 4 when x = 10
What is (3*7) divided by 5
Answer:
The answer is 4.2,
Hope that helped. x
Step-by-step explanation:
3 x 7 (3*7) = 21
21 divided by 5 = 4.2.
Answer:
4.2
Step-by-step explanation:
Using PEMDAS,
ParenthesisExponentsMultiplicationDivisionAdditionSubtractionWe know that to solve (3*7) divided by 5, we will need to solve what is in the parenthesis.
So, we need to figure out what is 7*3, which is 21.
This is what we have right now:
21 divided by 5
The next step is dividing,
We divide 21 by 5 to get 4Multiply the quotient digit (4) by the divisor 5Subtract 20 from 21Add a decimal place and a zero to the dividend, bring down the zero from the dividendDivided 10 by 5 to get 2Multiply the quotient digit (2) by the divisor 5Subtract 10 from 10The solution for the division is 4.2In the end, the answer is 4.2, hope this helped!
How to determine if Triangles are Congruent?
If they are, how do you know if they are SSS or ASA or SAS or AAS?
Essentially, how do I apply the different congruent thermos to the questions attached?
So basically what you have to do is first identify all of the sides or angles that equal eachother then you can see if you did a side side and side in a row etc, like 44 would be SAS because the vertical angles would be inbetween the two sides. 46 would be SSS because after you make the line in the middle for reflexive property you can see that there are three sides in a row.

Tracy bought a can of yellow paint to use on the table and chairs in her backyard. She used 1.25 liters of paint on the chairs. She has less than 3 liters of paint left for the table.
The inequality that describes the given problem is x - 1.25 < 3.
The given parameters:
Number of paints used on the chair, = 1.25 LitersNumber of paints left for the table, less than 3 litersLet the number of liters in one can of yellow paint = x
The following inequality can be used to represent the liters of paint left for the table.
the liters of paint left = x - 1.25
The liters of paint left is less than 3 liters;
x - 1.25 < 3
Thus, the inequality that describes the given problem is x - 1.25 < 3.

(I tried my best, sorry if it doesn't make sense.)
Step-by-step explanation:
Example: 1/4 - 1/8= ?
1: Find the common denominator (bottom number)
2: If the common denominator is 8 then you multiply 1/4 by 2/2 to get the denominator of 8. If you needed then you can multiply the other fraction to get the same denominator.
3: Once you get multiply that then you get 2/8 -1/8.
4: Subtract the numerator (top number) 1
5: Keep the numerator (8)
6: Your answer would be 1/8
