Question part points submissions used this exercise involves the formula for the area of a circular sector. find the area of a s

kolezko [41]

The formula for the area of a sector in radians is $A= \frac{1}{2}r^2 \theta$ , where theta is the angle in radians. For us, the formula looks like this: $A= \frac{1}{2}(9)^2* \frac{3 \pi }{5}$ . Doing all the multiplication on that gives us $A= \frac{243 \pi }{10}$ . Multiplying in pi and rounding to the nearest tenth gives us an area of 76.3 meters squared. You can use the formula for the area of a sector with the angle in degrees as well. Just replace the 360 degrees with 2pi and it works the exact same way.

Bob sees a very tall white pine tree. He estimates that the angle of elevation from him to the top of the tree is 77°

vlabodo [156]

Answer:

86.63 ft

Step-by-step explanation:

The tangent relation applies.

Tan = Opposite/Adjacent

tan(77°) = (tree height)/(20 ft)

tree height = (20 ft)·tan(77°) ≈ 86.63 ft

_____

<em>Additional comment</em>

It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.
