The circumference would be 16.328 mm.
Answer:
175.1
Step-by-step explanation:
Find the area of the semicircle:
(pi • radius²) / 2. [Radius is half of diameter]
(3.14 • 4²) / 2
(3.14 • 16) / 2
(50.24) / 2
25.12
Find the area of the parallelogram:
(base • height)
(30 • 5)
150
Add the areas of both shapes to get total area
25.12 + 150 = 175.12, round to the nearest tenths, 175.1
Hope this helps!
Answer:
Cost to travel 75 miles = 11.55 $
Explanation:
A scooter can travel between 22 and 28 miles on each gallon of gasoline.
Average distance a scooter can travel with each gallon of gasoline = (22+28)/2 = 25 miles.
One gallon of gasoline costs between $3.75 and 3.95 per gallon.
Average cost for one gallon of gasoline = (3.75+3.95)/2 = 3.85 $
We need to find cost for traveling 75 miles.
Gasoline required = Total miles/ Average distance a scooter can travel with each gallon of gasoline
= 75/25 = 3 gallons.
Cost to travel 75 miles = Gasoline required x Average cost for one gallon of gasoline
= 3 x 3.85
= 11.55 $
