<h3>
Answer: 71.96 cm</h3>
===========================================================
Explanation:
A full circle of radius r = 14 cm has a circumference of...
C = 2pi*r
C = 2*3.14*14
C = 87.92
This is the approximate distance around the circle, aka the perimeter.
Half of this is 87.92/2 = 43.96 which is the curved distance of this semicircle.
The straight line portion is 14+14 = 28 cm long.
The total perimeter of the semicircle shown is 43.96+28 = 71.96 cm
Answer:
66
Step-by-step explanation:
Find the last side of the triangle using the Pythagorean theorem.
B=
This makes b = 18.3
Now you can find the angle B = arcsin (opp/hyp)
B=arcsin
B= 66.42
Using angle bisector theroem, we have:
Solving for x, we get x= or x=3.75
So to find an average of things, you find the sum of the numbers, divided by the total numbers in the set.
So you add up 258 + 50 = 308.
Divide that by the total numbers (2). 308/2 = 154
