Asoup can is in the shape of a right cylinder. the can has a volume of 16 fluid ounces. the height is three times its radius. the metal used to make the lateral surface of the can costs $0.01 per square inch. the metal used to make the top and bottom costs $0.02 per square inch. if one fluid ounce is approximately 1.805 cubic inches, what is the total cost to make one empty soup can? use 3.14 for straight pi

$0.662772

Explanation:

v = Volume of can = 16 fl oz.

r = Radius of can

h = Height of can = 3r

Volume of cylinder is given by

h=3r\\\Rightarrow h=3\times 1.45247\\\Rightarrow h=4.35741\ in[/tex]

Surface area of sides is given by

Surface area of top and bottom is given by

Cost of making the can will be

The cost to make the can is $0.662772

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
