A fire ranger stands atop an observation tower 70 feet above the ground and sees a fire in the distance. She measures the angle

mrs_skeptik [129]

Answer:

$103.78\:\mathrm{ft}$

Step-by-step explanation:

We can form a right triangle where the distance between the ranger's current position and fire is the hypotenuse of the triangle. In a right triangle, the tangent of an angle is equal to its opposite side divided by the hypotenuse.

Therefore, we have:

$\tan 34^{\circ}=\frac{70}{x}$ , where $x$ is the distance between the base of the tower and the fire.

Solving, we get:

$x=\frac{70}{\tan 34^{\circ}}=103.779267796\approx \boxed{103.78\:\mathrm{ft}}$

Answer:

Circumference = 39.6 cm

We know:

Circumference of a circle = 2πr

⇒39.6 =2×

×r⇒

39.6×7

2×22

=r⇒r=6.3 cm

Also,

Area of the circle = πr2

×6.3×6.3=124.74 cm2
