Basic math plz help
volume of a cylinder with the given height and radius or diameter problems.

The volumes of the given cylinders ;

1. 125.6 cubic inches, 2. 62,800 cubic cm, 3. 2,009.6 cubic mm, and 4. 2,289.26 cubic feet.

The volumes of the given spheres;

1. 523.33 cubic cm, 2. 7,234.56 cubic inches, 3. 4.1866 cubic feet, and 4. 38,772.92 cubic mm.

Step-by-step explanation:

Step 1:

The volume of any cylinder is given by π times the product of the square of the radius (r²) and the height (h).

The volume of any cylinder, .

Step 2:

1. d = 4 inches, r = 2 inches, h = 10 inches, cubic inches.

2. r = 20 cm, h = 50 cm, cubic cm.

3. d = 16 mm, r = 8 mm, h = 10 inches, cubic mm.

4. r = 9 feet, h = 9 feet, cubic feet.

Step 3:

The sphere's volume is given by multiplying with π and the cube of the radius (r³).

The sphere's volume , .

Step 4:

1. r = 5 cm, , cubic cm.

2. d = 24 inches, r = 12 inches, ,  cubic inches.

3. r = 1 foot, , cubic feet.

4. d = 42 mm, r = 21 mm, ,  cubic mm.

where is abdul's work? don't see that anywhere posted : /

step-by-step explanation:

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
