Step-by-step explanation:
lets radius be r and height be h,
r+h=21 -----(1)
curved surface area
2×pi×r×h=616 -----(2)
use simultaneous eqn to solve for r and h.
total surface area of cylinder= 2×pi×r×h + 2×pi×r²
= ans if im not wrong
Answer:the ration to x and b that equals c is about 3 dollars

Answer: w = 50
Step-by-step explanation:
4.5w - 5.1w = -30
-0.6w = -30
0.6w = 30
W = 50
