Answer:
<em>AB = 3π</em>
Step-by-step explanation:
<em>See attachment for correct format of question.</em>
Given
From the attachment, we have that
θ = 20°
Radius, r = 27
Required
Find length of AB
AB is an arc and it's length can be calculated using arc length formula.
<em>Substitute 20 for θ and 27 for r</em>
Hence, the length of arc AB is terms of π is 3π
Answer:
11
Explanation:
(next time, it would be helpful to include a picture)
If you were on the same test as I was, than that means that the triangle you're looking for is the one below.
Using the Pythagorean Theorem,
a² + b² = c² is the same as c² - b² = a²
c = 61
61^2 = 61 X 61 = 3,721
b = 60
60^2 = 60 X 60 = 3,600
Next, we subtract:
3,721 - 3,600 = 121
√121 = 11
(x = 11 cm)
so 11 is your answer
