Answer:
Step-by-step explanation:
Given:
Perimeter of the semi-circle = 60 m
let the radius of the semi-circle to be 'r'
Also,
Perimeter of the semi-circle = πr + 2r = ( π + 2 ) × r
on equating, we get
( π + 2 ) × r = 60 m
or
r =
now,
the area of the semi circle = πr² / 2
on substituting the value, we get
area =
or
area =
Hence,
the area of the semi-circular region =

Answer:
I’m not sure about the other questions but #3 is 62 because a line is equal 180 and they give u 118 so 180-118=62 and number #5 is b vertical angles because b is 50degree and its the same as the one across from it
