identify the diameter of Q given that a= 169 pie in2
Answer:
the diameter will be D=26 in.
Step-by-step explanation:
The area of a circle is given by:
[tex]A=\pi R^{2}[/tex] (1)
Where:
A is the areaR is the radius of the circleNow, we know that A = 169 π in²
So, we just need to use equation 1 to find R.
[tex]169\pi = \pi R^{2}[/tex]
[tex]R=\sqrt{169}[/tex]
[tex]R=13 \: in[/tex]
Therefore, the diameter will be D=2*R=26 in.
I hope it helps you!
The diameter of the circle is 26 inches
The area of the circle is given as:
[tex]A = 169\pi[/tex]
The area of a circle is calculated as:
[tex]A = \pi r^2[/tex]
By comparison, we have:
[tex]\pi r^2 = 169\pi[/tex]
Divide both sides of the equation by pi
[tex]r^2 = 169[/tex]
Take the positive square roots of both sides
[tex]r = 13[/tex]
Multiply by 2, to calculate the diameter
[tex]d =2 * 13[/tex]
[tex]d = 26[/tex]
Hence, the diameter of the circle is 26 inches

A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
54 feets
2.5 inches
Step-by-step explanation:
Given that:
Scale model:
5 in : 9ft
If 5 in = 9 ft
Hence, 1 in on the blue print equals
5 in = 9 ft
1 in = x
Cross multiply
5x = 9
x = 9/5 feets
Hence, 1 inches on the blueprint equals 9/5 feets actual
Blueprint length (in.) ___ Actual length (ft)
5 _________ 9
10 ________ 18
15 ________ 27
20 _______ 36
25 _______ 45
30 _______ 54
Hence ;
5 * 9/5 = 9 feets
10 * 9/5 = 18 feets
15 * 9/5 = 27 feets
20 * 9/5 = 36 feets
25 * 9/5 = 45 feets
30 * 9/5 = 54 feets
Window with actual width of 4.5 feets
Width of window in blue print :
Actual width ÷ 9/5
Actual width = 4.5 = 4 1/2 = 9/2
9/2 * 5 /9
= 5 /2
= 2 1/2 inches = 2.5 inches

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%
9514 1404 393
Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%
