Alice purchased paint in a bucket with a radius of 3.5 inches and a height of 8 inches the paint cost $0.05 per cubic inch.

what was the total cost of the paint?

use 3.14 for pi.

round only your final answer to the nearest penny.

enter your answer in the box.

$ ∛

  $15.39

Step-by-step explanation:

The volume of the cylinder is given by ...

  V = πr²h = 3.14·(3.5 in)²·(8 in) = 307.72 in³

Since each cubic inch costs $0.05, the total cost is ...

  $0.05 · 307.72 ≈ $15.39

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

the correct answer is x/3+10≥32

hope this !
