Solution :
Given that :
The radius of circle A = 6 cm
The radius of circle C = 4 cm
In circle A
The length of arc EF = 
= 14.653 cm
In circle C
The length of arc GH =
= 9.769 cm
Therefore,
The length of EF is 14.653 cm
The length of GH is 9.769 cm
The length of EF is 1.5 times the length of GH
i.e. 14.653 = 1.5 x 9.769
14.653 = 14.653
Hence proved.
Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
Answer:
Should be 36°
Step-by-step explanation:
If you add up the angle measurements of the shape, it should equal 360° (This applies to all shapes)
So 360° divided by 10 (# of angles)= 36° (Per angle)
Answer: The diameter 7.2 inches and circumference 28 inches of the same circle could not possible.
Step-by-step explanation: Given diameter of the circle = 7.2 inches.
Circumference of the circle = 28 inches.
Formula for Circumference of the circle = πd, where d is the diameter of the circle.
Plugging value of d in formula, we get
Circumference of the circle = π(7.2).
Plugging π= 3.14, we get
Circumference = 3.14 (7.2) = 22.61.
22.61 is smaller than given circumference 28 inches.
<h3>
Therefore, the diameter 7.2 inches and circumference 28 inches of the same circle could not possible.</h3>
