Calculate the volume of this regular solid

which solid?

Explanation:

the volume of any solid is basically the area of base into the height or altitude of the solid

if given a certain solid i could give you the formula for its volume

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

answer is slate

hope this
