Answer:
p = 9π + 18 miles Exact answer
p = 46.26 miles decimal approximation
Step-by-step explanation:
The whole circumference of a circle is
c = 2πr
Half a circle's circumference plus the diameter would be the semicircle's perimeter
p = (1/2)2πr + 2r
p = πr + 18
p = 9π + 18 miles Exact answer
p = 3.14 * 9 + 18
p = 46.26 miles decimal approximation
Answer:
Good luck, do well
Step-by-step explanation:
Answer:
Step-by-step explanation:
x + 3y = - 28
y = -5x
x + 3(-5x) = -28
x -15x = -28
-14x=-28
x=2
y = -5(2)
y=-10
