Answer:
50.2 m^2
Step-by-step explanation:
The Area of a circle is given by the equation pi(r)^2
Therefore if r = 4 we can plug it into the equation to get:
pi (4)^2= pi(16)= 50.2655 or about 50.2 m^2Related Questions

Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
There are infinitely many values of x and y are possible.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Two school groups go to a roller skating rink.
One group pays $243 for 36 admissions and 21 skate rentals.
The other group pays $81 for 12 admissions and 7 skate rentals.
Let x represent the cost of admission and let y represent the cost of a skate rental.
We have a system of equations,
36x + 21y = 243 {equation 1}
12x + 7y = 81 {equation 2}
Simplifying equation 1 we get,
36x + 21y = 243
Divide by 3,
12x + 7y = 81
That means, there are infinitely many solutions possible.
Therefore, there are infinitely many solutions possible.

The question is down below and I would really appreciate the help!
Answers
Answer:
y = 3x
Step-by-step explanation:
from the table slope or rate of change is
m = 6 - 0 / 2 - 0 = 6/2 = 3
m = 12 - 6 / 4 - 2 = 6/2 = 3
m = 18 - 12 / 6 - 4 = 6/2 = 3
so m = 3
y = mx + c
c is y intercept --> y value when x is 0
y = 0 = c
so line equation is y = 3x + 0
y = 3x
Answer:
B, or 3x.
Step-by-step explanation:
When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.
2 x 3 = 6
4 x 3 = 12
6 x 3 = 18
Therefore, your answer is 3x.

Fill in the next two terms in the pattern. Enter your answers in the boxes.
0.16, 0.35, 0.54,
,
Answers
Answer:
By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.
Step-by-step explanation:
Answer:
0.73 and 0.92
Step-by-step explanation:
The difference of the first 3 is 0.19 per step, so continuing that is 0.73 and then 0.92

A band earns $\frac{2}{3}$
of their profit from selling concert tickets and $\frac{1}{5}$
of their profit from selling merchandise. The band earns $1500 from selling concert tickets. How much money does the band earn from selling merchandise?
Answers
Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.
(2/3) / (1/5) = 10/3 = 3 1/3
Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.
This can be elaborate in such a way also.
Let suppose the total profit is $30.
then the profit from the ticket sale = 2/3 of 30 = $20
and the profit from the band merchandise sales = 1/5 of 30 = $6
Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.

An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?
Answers
Answer:
You can purchase 10 songs after buying 12 videos.
Step-by-step explanation:
Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.
Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.
Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.
