Step-by-step explanation:
<u>Surface Area of a Cylinder</u>
Given a right cylinder of base radius r and height h, the surface area is calculated as follows:
The cylindrical tank has a height of h=1 m and a base diameter of 140 cm. The radius is half the diameter, thus r=140/2 = 70 cm = 0.7 m. Substituting:

Answer:
112.5
Step-by-step explanation:
24x=2700
=> x= 2700/24
= 112.5
Therefore, x= 112.5
Answer:
3 necklaces and 12 bracelets
Step-by-step explanation:
Bracelets = x +4
amount of necklace gold = 20*x
amount of gold in bracelet = 7*(x+4)
added together = 109 gm
20x + 7(x+4) = 109
20x + 7x+28 = 109
27x+28=109
-28 -28
27x= 81
/27 /27
x=3 necklaces
then bracelets = 3+4=12
