Answer:
21
Step-by-step explanation:
If she arrives by boat;
The distance she needs to row = Lake diameter
Distance = Lake diameter = 2 x Radius
Boat distance = 2 x 2 miles = 4 miles
So;
When moving on foot
The distance that needs to be moved D = Half of the circle circle
∴ D = π × Radius
The distance that needs to be moved D = π × 2 miles = 2π Miles
Arc length = Radius × θ
String length = radius x 2 x sin (θ / 2)
0 ≤ θ ≤ π, 0 ≤ sin (θ / 2) ≤ 1

Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
A semicircle is given with radius of 3cm .
And we need to find the perimeter of the semicircle . We know the perimeter as ,
Perimeter = πr
Perimeter = 3cm × π
Perimeter = 3π cm .
Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,
Perimeter = 3π + 6 cm
We were supposed to give answers in terms of π .
<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
Answer:
8/15
Step-by-step explanation:
Using Pythagorean Theorem the length of XZ is 15.
tan X = opposite / adjacent = YZ / XZ = 8 / 15.
