Find the radius of a cylinder if the lateral surface area is 36 (I think it is the pie symbol,
it looks like a small cursive n with a line on top of it) cm squared and the height of the cylinder is 3 cm.
:
Lateral surface area:
2%2Api%2Ar%2Ah+=+A
;
h=3; and A+=+36%2Api
2%2Api%2Ar%2A3 = 36%2Api
divide both sides by 2%2Api; results:
3r = 18
r = 6 cm
