Dang what kinda math they teaching you! that makes no sense! ill try and help though
Common denominator would be 40, 3/4 becomes 30/40, 1/5 becomes 8/40, 5/8 becomes 25/40. 10 30/40 + 6 8/40 + 12 25/40 = 28 63/40 = 29 23/40
SA = 2πr(r+h)
= 2π7(7+15)
=308pi
48
the answer is 48 i’m just writing this because it says i have to write something 20 words long
