Answer:
Q12 ) 26635.2 feet^3
Q13 ) 6838.9 inches^3
Q14 ) 1934.4 feet^3
Q15 ) 339120 meters^3
Explanation:
Question 12 -
Use the formula for the volume of a cylinder which is:
V = πr^2h
Substitute the given values from the problem into the formula:
V = 3.14 × 18.8^2 × 24
V = 26635.23...
V = 26635.2 feet^3 (nearest tenth)
Question 13 -
Use the formula for the volume of a cylinder which is:
V = πr^2h
Substitute the given values from the problem into the formula:
Note:
Radius = Diameter ÷ 2
Therefore, in this problem, divide the diamater (22) by 2 to get the radius (11).
V = 3.14 × 11^2 × 18
V = 6838.92
V = 6838.9 inches^3 (nearest tenth)
Question 14 -
Use the formula for the volume of a cylinder which is:
V = πr^2h
Substitute the given values from the problem into the formula:
V = 3.14 × 5.55^2 × 20
V = 1934.397
V = 1934.4 feet^3 (nearest tenth)
Question 15 -
Use the formula for the volume of a cylinder which is:
V = πr^2h
Substitute the given values from the problem into the formula:
V = 3.14 × 60^2 × 30
V = 339120 meters^3
