Find the volume of the cylinder whose core has been removed

or around 157.08 cubic units

Step-by-step explanation:

To find the answer here, you can start by finding the volume of both cylinders, and subtracting the smaller from the larger. The volume of the larger cylinder is . The volume of the smaller cylinder is cubic units. Hope this helps!

50π or 157.079632679≈157 units³

Step-by-step explanation:

We need to find the area of the original cylinder and the core. Then subtract the volume of the core from the original cylinder's volume.

Formula for the volume of a cylinder is: πr²h

Original Cylinder:

π*3²*10=

π*9*10=

90π is the volume of the original cylinder

Original Cylinder's core:

π*2²*10=

π*4*10=

40π is the volume of the original cylinder's core.

90π-40π=50π

So the cylinder without it's core's volume is 50π

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
