What are all the subsets of the set? {-8,4} a. ø, {-8}, {4} b. {-8}, {4}, {-8, 4} c. {-8}, {4} d. ø, {-8}, {4}, {-8, 4}

I am sorry. but i dunno. not rilly good @ this kinda math. very sorry. but i AM good @ other subjects & other TYPES of math, tho.

Step-by-step explanation:

it should be a.

hope it

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
