A. for the circumference it is C=pi(d)=pi(2r)=pi(10)=  31.4 ft
b. for the area it is A=pi(r)^2=pi(5)^2=pi(25)= 78.5 ft squared
c. since the are is 78.5 ft squared multiply by $4.50= $353.25 to floor the circle.

Ben is spending his summer driving across the country. He is going to spend the first day
KengaRu [80]

Answer:

The graph of the data presented is shown in the attached image to this solution.

It shows that the relationship between distance travelled in miles and the time take in hours is D = 55t

Step-by-step explanation:

The distance travelled with the corresponding time taken are presented in the table

Note: D - Distance travelled (miles)

t - Time (hours)

D | t

55 | 1

110 | 2

165 | 3

220 | 4

275 | 5

330 | 6

We are then told to plot these distance travelled on a graph with the time taken.

The distance travelled is plotted on the y-axis and the time in hours is plotted on the x-axis.

The image of the graph of this function will be attached to this answer

It is evident that the graph shows the relationship between the distance travelled and time taken to be D = 55t

Hope this Helps!!!

Find the real zeros of the trigonometric function on the interval 0 ≤ x < 2π
Romashka-Z-Leto [24]
F(x) = 4 [cos (x)]^2 - 3 = 0

4[cos(x)]^2 = 3

cos(x) = √3 / 2

That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.

Answer: x = 30 degrees and x = 330 degrees

Check my answer? Please, no joking around guys.
WITCHER [35]
This is a right angle triangle 
So we can use the tangent 
tan x = 5/20 
tan x= 0.25 
x=tan^-1 (0.25) 
x= 14.04 degrees 
So yes you're correct
