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

Step-by-step explanation:
Answer:
A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?: √3170≈56.3 km.
A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?: √44.19≈6.65 ft.
Step-by-step explanation:
For these questions, we will need to use the pythagorean theorem: a²+b²=c², where a and b are the legs of the right triangle and c is the hypotenuse.
A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?
In this question, we are looking for the hypotenuse.
19 and 53 are the legs of the triangle, so we can plug it into the equation:
19²+53²=c²
361+2809=c²
3170=c²
√3170=c
56.30275304103699, or approximately 56.3 km.
A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?
25 is the hypotenuse since it is leaning sideways and is the longest side. 24.1 is one of the legs.
In this question, we are looking for one of the legs.
Let's plug it in: 24.1²+b²=25²
580.81+b²=625
Subtract 580.81 from both sides.
b²=44.19
b=√44.19
6.647555941848102, or approx. 6.65 ft.
A vending machine has $50.40 in it. There are 432 coins total and the machine only accepts nickels and quarters. How many nickels and quarters are in the machine?
Answers
Quarters = q
n + q = 432
Nickels are 5 cents (0.05)
Quarters are 25 cents (0.25)
0.05n + 0.25q = 50.40
Use substitution or elimination (I like substitution)
n + q = 432 means n = 432 - q
So 0.05n + 0.25q = 50.4 is
0.05(432 - q) + 0.25q = 50.4
21.6 - 0.05q + 0.25q = 50.4
21.6 + 0.2q = 50.4
0.2q = 28.8
q = 144
Plug in to find nickels
n + q = 432 means
n + 144 = 432
n = 288
