Area of a circle = pi x r^2
Area of circle = 150,000/ 1578 = 95.06 square miles
95.06 = 3.14 x r ^2
Divide both sides by 3.14
R^2 = 30.27
Find the square root:
R = sqrt(30.27)
R = 5.5
The radius is c) 5.5 miles
Average speed = (total distance covered) / (time to cover the whole distance)
Total distance = (516 + 368) = 884 yards
Total time = (6 + 4) = 10 minutes
Average speed = (884 yards) / (10 minutes)
Average speed = 88.4 yards/minute (C)
Other ways to write the same speed:
-- 4.42 feet/second
-- 265.2 feet/minute
-- 53.04 inches/second
-- 5,304 yards/hour
-- 3.014 mph (rounded)
-- 810.07 furlong/fortnight
The <em><u>correct answer</u></em> is:
C. Range
