Answer:
56.52
Step-by-step explanation:
This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52

Answer:
A = $759.23 after 5 years
Step-by-step explanation:
The compound interest formula applicable here is
A = P(1 + r/n)^(nt), where n is the number of compounding periods per year.
Here P = $550, r = 0.065, n = 4 and t = 5.
We get A = $550(1 + 0.065/4)^(4*5), or
A = $550(1 + 0.01625)^20, or:
A = $759.23
Answer:
B) 40
Step-by-step explanation:
<em>Average speed = distance/time</em>
Distance = 12750 km
Time = 13.5 days = 13.5*24 hours = 324 hours
Speed = 12750 km /324 h = 39.4 km/h ≈ 40 km/h
<u>Correct option is</u> B) 40
