A cylindrical pail that has the base area of 9 pi inches squared and a height of 10 inches. One friend bought a pyramid mold wit

FromTheMoon [43]

Answer:

cylinder — 90π in³
pyramid — 37 1/3 in³
cone — 12.5π in³

Step-by-step explanation:

The volume of a cylinder is given by ...

V = Bh . . . . . where B is the base area and h is the height

The volume of a pyramid or cone is given by ...

V = (1/3)Bh . . . . . where B is the base area and h is the height

The area of a square of side length s is ...

A = s²

The area of a circle of radius r is ...

A = πr²

___

Using these formulas, the volumes of these objects are ...

cylinder: (9π in²)(10 in) = 90π in³

square pyramid: (1/3)(4 in)²(7 in) = 37 1/3 in³

cone: (1/3)(π(2.5 in)²)(6 in) = 12.5π in³ . . . . slightly larger than the pyramid

Identify the composite function and its domain

creativ13 [48]

$f(g(x))=f(\sqrt{x-2})$
$f(g(x))=3(\sqrt{x-2})^{2}+4$
$f(g(x))=3(x-2)+4$
$f(g(x))=3x-6+4$
$f(g(x))=3x-2$

Domain:
g(x) must be greater than or equal to zero (no square roots of negative numbers) therefore x must be greater than or equal to 2. Answer is B.

Centroid: Find AD if HD=24.

astraxan [27]

Centroid is commonly used with a triangle. It is the average of the lines presented in the triangle. So in this situtation the Centroid is 24. the reason is because the line segment is 24, so we do 24/1. The 1 is for how many lines there is, which is one.

Does the system of equations have no solution, one solution, or an infinite number of solutions? −5x+y=−1−5x+y=10

kherson [118]

Answer:

5x-y=9, y=5x+19 write both equations in same formy=5x-9 for the first and havey=5x+19 for the second. These are two parallel lines with different intercepts. They do not intersect or coincide. No solutions

and y=6x+14, 12x-2y=-28 write both equations in same formy=6x+142y=12x+28 or y=6x+14. They are the same line. The solution is all of the points on the line.

Step-by-step explanation:

I hope it will help you have a great day bye and Mark brainlist if the answer is correct I am sorry if the answer is worng
