Q12 ) 26635.2 feet^3

Q13 ) 6838.9 inches^3

Q14 ) 1934.4 feet^3

Q15 ) 339120 meters^3

Step-by-step 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

what the question so we can you out

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
