Answer:
5.14 km
Step-by-step explanation:
A semicircle is 1/2 of a circle so the perimeter is just 1/2 of the circumference
C = 2 * pi r for a circle so for a semicircle
1/2* 2* pi *r
pi*r
3.14 * 1
3.14
If we want to include the piece that closes the semicircle, we need to add the diameter
d = 2r = 2(1) = 2
2+3.14 = 5.14
Answer: 2.2214
Step-by-step explanation:
0.07 x 39.98 = 2.7986 (is tax)
2.7986 + 39.98 = 42.7786
45.00 - 42.7786 = 2.2214
