Answer:
0.15 I believe
Step-by-step explanation:
you just divide
Answer:I think it’s option d
Step-by-step explanation:
To find the circumference of a circle, you can use the formula
πd, where d is the diameter of the circle.
In this instance, we can tell from the picture that the diameter of the circle is 16 inches.
Therefore, the exact circumference of the circle is
C. 16pi inches
We are given that:
Model [length = 35 cm; wingspan = 66.9 cm; height = ?]
Actual [length = 21 ft 1 in = 6.43 m; height = 2.74 m; wingspan = ?]
We can solve for the height of the model plane using the given values of the actual plane and by ratio and proportion:
35 cm / height model = 6.43 m / 2.74 m
height model = 14.9 cm
We can also solve for the wingspan of the actual plane:
35 cm / 66.9 cm = 6.43 m / wingspan actual
wingspan actual = 12.30 m
So we can see that the model is:
6.43 m (100 cm / m) / 35 cm = 18.37
18.37 times smaller than the actual plane
