Answer:

Option B 63°

Step-by-step explanation:

we know that

If the ray is tangent to the circle

then

a°+b°=90° -----> by complementary angles

Remember that

The inscribed angle measures half that of the arc comprising

<u><em>Find the measure of inscribe angle a</em></u>

∠a=(1/2)[54°]=27°

Find the measure of angle b

a°+b°=90°

substitute

27°+b°=90°

b°=90°-27°=63°

Answer:

$V_{cylinder}=3584\pi \thinspace yd^3$

Step-by-step explanation:

Volume of a cylinder is just the area of the circle-surface multiplied by the height of the cylinder.

$V_{cylinder}=\pi r^2 h$

We're given that the radius=8 and height=56

$V_{cylinder}=\pi r^2 h$

$V_{cylinder}=\pi (8)^2 (56)$

$V_{cylinder}=3584\pi \thinspace yd^3$

for the formula is

Y = starting population x (1-rate of change)^number of years

2010-2001 = 9

Y= 567 x (1-0.015)^9 = 494.89, round up to 495 people
