The radius= 4.21 cm
The circumference of the circle is 26.44 cm.
we have given that
Area = 62 square centimetres.
What is the formula for the area of circle
[tex]A=\pi r^{2}[/tex]
A=62 and pi=3.14
[tex]62=3.14r^{2}[/tex]
find the value of r square divide both side by 3.14
[tex]r^2=\frac{62}{3.14}[/tex]
[tex]r^2=17.75\\[/tex]
[tex]r=4.21cm[/tex]
[tex]circumference of circle =2\pi r[/tex]
[tex]C=3.14)(4.21)\\\\C= 2 (13.22) \\\\C= 26.44.cm[/tex]
Therefore we get,
The radius= 4.21 cm

Answer: Y = 7/8x+ 2.25
Step-by-step explanation:
you would subtract both y 7 subtract both x -8 y=7/8x+b 3= 7/8 x-2 +b 3 = 1.75 + b -1.75 -1.752.25 = bAcetaminophen is a common pain reliever and fever reducer. Here is a graph showing the amount of acetaminophen, in milligrams, in an adult's body at different times after they take a normal dose. 1. What is the vertical intercept? What does it mean in this situation? 2. What fraction of the medicine remained after one hour? 3. Write an equation that represents the amount of medicine, a, after t hours.
Answer:
I don't know 1
2. 3/4
3. y= 1000(0.75)^x
Step-by-step explanation:
According to the information depicted on the graph:
Vertical intercept = 1000This is the initial Value of acetaminophen in the body just after taking the normal dose ; At time, t = 0Fraction left after 1 hour = 0.75Amount after t hours = [tex]y(t) = 1000(0.75)^{t}[/tex]The vertical intercept is the value of the y - intercept, where the line crosses the y - axis. ; vertical intercept = 1000
The y - intercept is the amount of the drug in the body 0 minutes after taking it.
Fraction of drug left after one hour :
t(1) ÷ t(0) = 750 / 1000 = 3/4 = 0.75Amount of medicine left after t hours :
Initial amount(rate of decrease)^time[tex]y(t) = 1000(0.75)^{t}[/tex]
Hence, the function which models the graph is [tex]y(t) = 1000(0.75)^{t}[/tex]

Cassidy the Clown does face painting at the city carnival. She paints 8 faces every 21 minutes. Write an equation that related the number of faces she paints (y) and the time she spends painting (x)
ANSWER WITH A PICTURE ASAP
Answer:
8y=21x
Step-by-step explanation:
i'm not sure how to draw this out in a picture but the equation is above.
like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.
in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.
hope this helps, if it did please make sure to leave a like, rate, and give me the brainliest if possible!
thanks have a great day!
What is the best buy for the following advertise sale on pop A(eight cans for $4.88 B(10 cans for $5.80 or C(3 cans for d cans for $7.20
Buying 10 cans for $5.80 is the best deal.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
We have
Cost of eight cans is $4.88
⇒ cost of one can = [tex]\frac{4.88}{8}[/tex] = $0.61
Cost of 10 cans is $5.80
⇒ cost of one can = [tex]\frac{5.80}{10}[/tex] =$0.58
Cost of 3 cans is $7.20
⇒ cost of one can = [tex]\frac{7.20}{3}[/tex] = $2.4
Hence, buying 10 cans for $5.80 is the best deal.

a. 1
b. any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
Step-by-step explanation:
Answer and explanation:
a) This value is equal to one because it is just the number divided by itself.
b) Since any number divided by itself is equal to 1, 6^3/6^3 also has to equal to one. This also means that when we bring the 6^3 up to the numerator, the equation 6^3-3, which simplifies into 6^0 also has to equal 1, because it is equivalent to being divided by itself.

b) Solve the linear system to find the cost of a turkey sub and the cost of a veggie sub.
Answer:
4/9 of sales are veggie 5/9 are turkey
4/(4+5)=4/9
5/(4+5)= 5/9
4/9 x 27 = 12
5/9 x 27 = 15

What is the relationship between sin x and cos y?
Answer:
It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).
