B. 102.57 cu. cm is the answer
Solution:
V=πr^2h
The diameter is 14. To find the radius you divide the radius by 2 which is equal to 7. [Radius is 2 times diameter]
V= 3.14×7×7×2
V= 102.57
Answer:
Number of days= 5.2 days
Step-by-step explanation:
Giving the following information:
Daily distance traveled= 250 miles
Total number of miles= 1,300 miles
<u>To calculate the number of days to cover 1,300 miles, we need to use the following formula:</u>
Number of days= total distance / daily distance traveled
Number of days= 1,300 / 250
Number of days= 5.2 days
Blue car:
28 1/2 miles = 28.5 miles
1/14 gallons = 0.0714 gallons
28.5 miles/(1/14 gallons) = 392.15 miles/gallon
48.15 because 7% of 45 is 3.15, and 45+3.15 is 48.15
