1f 1 sin A + 1 sinB + 1 sinC =0. prove that: (sin A + sin B + sin C) ^ 2 = sin^2 A + sin^2 B + sin^2 C.

the radius is 2 times the diameter.

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

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
