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:
x = 9.4 and y = 8
Step-by-step explanation
If you're using a calculator to solve this, make sure it's in Degree mode.
Solve for x:
Sin(32) = =
bring x to one side
x = = 9.4
Solve for y:
Tan(32) = =
bring y to one side
y = = 8
