A hollow metallic cylinder is made from a metallic sheet of 2.4 cm thickness. The inner radius of the cylinder is 5.8 cm and the length is 50 cm. Find the volume of the metal used.
step by step explain plz​

The volume of the metal used is 5277.9 cm³.

Step-by-step explanation:

The volume of a cylinder is given by:

Where:

r: is the radius

h: is the height = 50 cm

The volume of metal () can be found by subtracting the internal volume () from the external volume ():

The external radius is given by the sum of the internal radius with the tickness:

Hence, the volume is:

Therefore, the volume of the metal used is 5277.9 cm³.

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
