I believe it would be 2,376.66 but due to rounding it should be 2,377
Answer:
A. 16.12 ft B. 9.64 ft
Step-by-step explanation:
For both of these, you need Pythagorean's Theorem because we have right triangles. In part A, we are given 2 legs and are asked to find the length of the hypotenuse:
and

and PR = 16.12 ft
In part B, we are given the length of the hypotenuse and side PQ remains the same:
and

so
QR = 9.64 ft
90+70= 160
Then 180-160=20
So angle A is 20
Let the radius of the circle be x, then by the tangent-secant theorem
4^2 = 2(x + 2)
16 = 2x + 4
2x = 16 - 4 = 12
x = 12/2 = 6
Therefore, the radius of the circle is 6 inches.
I believe it is 2,400. 4,000 x 0.6 = 2,400
