Answer:
7 feet
Step-by-step explanation:
Volume of a cyclinder = πr^2h
Volume of a cyclinder = 1952
π = 3.14
r = ?
h = 2r
Volume of a cyclinder = πr^2h
1952 = 3.14 * r^2 * 2r
1952 = 3.14 * 2r^3
1952 = 6.28r^3
Divide both sides by 6.28
r^3 = 1952 / 6.28
= 310.83
r^3 = 310.83
Find the cube root of both sides
r = 6.77 feet
Approximately 7 feet
Answer:
9000 ft
Step-by-step explanation:
Given: A airplane is ascending at a constant rate of 15 feet per second,
What we need to know: The change in altitude during 10 minutes of flight,
60 seconds = 1 minute
60 × 10
= 600 seconds
600 × 15
= 9000 ft
Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.
Kilometers per hour and miles per hour would be the most reasonable to measure someone running a race. Millimeters and inches are too small.
Answer: 30º
Step-by-step explanation: Draw a line of 5cm. Draw another line at an end that is 8cm and has an angle of 90º between them. Join the ends of the lines. Measure the smallest angle and it should be 30º.
