The area of a circle is PI x r^2
25PI = PI x r^2
Divide both sides by PI:
25 = r^2
Take the square root of both sides:
Radius = 5 inches.
Answer:
5 is the radius.
Step-by-step explanation:
Since the formula for area in a circle is [tex]\pi r^{2}[/tex], we can substitute 25 for r squared.
Since 25 is equal to r squared, it means that r is equal to 5.
5 is the radius.

PLS HELP
GEOMETRY
Answers
9514 1404 393
Answer:
ZV ≈ 42.8
Step-by-step explanation:
WZ and ZX and ZY are each radii of the incircle, so are the same length.
8x -22 = 3x +8
5x = 30
x = 6
ZX = ZY = 3x +8 = 3(6) +8 = 26
ZV is the hypotenuse of right triangle ZVY, which has side lengths of 34 and 26. So, the length of ZV can be found from the Pythagorean theorem as ...
ZV = √(34² +26²) = √1832
ZV ≈ 42.8

y-2 = -3(x + 6), write the equation of the line in slope intercept form.
Answers
Answer: y=-3x-16
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is slope and b is y-intercept.
y-2=-3(x+6) [distribute]
y-2=-3x-18 [add both sides by 2]
y=-3x-16
Now, we see that the equation above matches the slope-intercept form equation. You can see that m=-3 and b=-16.

kilometers from the runway. What is the angle of depression for the descent of the plane?
Round to the nearest degree.
Answers
Answer:
Angle of depression = 3.37°
Step-by-step explanation:
We are told that A plane flies at an altitude of 3.5 kilometers and then starts to descend when it is 60
kilometers from the runway.
I've attached an image of a triangle depicting this question.
From the triangle, we can find the angle of depression θ from trigonometric ratio since it's a right angle triangle.
Thus;
3.5/60 = tan θ
tan θ = 0.0583
θ = tan^(-1) 0.0583
θ = 3.37°

a corner self is 1/4 of a circle and has the radius of 10.5 inches. enter the area of the self in square inches. can you round it to nearest hundredth?
Answers
Answer:
The area of the shelf is 86.59 square inches
Step-by-step explanation:
The formula of the area of the circle is A = π r², where
r is the radius of the circle∵ The corner shelf is [tex]\frac{1}{4}[/tex] of a circle
→ That means its area is [tex]\frac{1}{4}[/tex] the area of the circle
∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × area of the circle
∵ Area of the circle = π r²
∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × π r²
∵ The radius of the shelf is 10.5 inches
∴ r = 10.5 inches
→ Substitute the values of r in the formula of the area
∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × π × (10.5)²
∴ The area of the corner shelf = 86.59014751
→ Round it to the nearest hundredth
∴ The area of the corner shelf = 86.59 square inches
∴ The area of the shelf is 86.59 square inches

Answer the following parts asked.
Answers
Answer:
[tex]f(n) = 15 + (n + 1)[/tex]
Step-by-step explanation:
Tina earns $15 every week when she mows the lawn.
We would put $15 because she earns $15 every week.
She earns 15 every week, so we would put (n + 1).
Our final answer would be [tex]f(n) = 15 + (n + 1)[/tex]
Answer:
The explicit rule is:
[tex]f(n)=60+15(n-1)[/tex]
After 15 week, Tina will have $270 in her savings account.
Step-by-step explanation:
Let’s write down our sequence so we can see it better.
For the first week (i.e. the first term), Tina has $60.
For the second week (i.e. the second term), Tina has $75.
And for the 3rd, 4th, 5th, and 6th week, Tina has $90, $105, $120, and $135, respectively.
Therefore, we can write the following sequence:
60, 75, 90, 105, 120, 135...
Note that our initial term a is 60.
And our common diffference will be 15.
Let’s find the explicit rule. The standard format for an explicit rule is:
[tex]f(n)=a+d(n-1)[/tex]
Where a is the initial term and d is the common difference.
Let’s substitute 60 for a and 15 for d. Hence, our explicit formula is:
[tex]f(n)=60+15(n-1)[/tex]
So, to find the amount Tina will have in her savings account in 15 weeks, we will substitute 15 for n and evaluate. So:
[tex]f(15)=60+15(15-1)[/tex]
Evaluate:
[tex]\begin{aligned} f(15)&=60+15(14) \\ f(15)&=60+210 \\ f(15)&=270 \end{aligned}[/tex]
Hence, after 15 weeks, Tina would have $270 in her savings account.
