Answer:
It's required 
of sheet for the tank
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:
It's required of sheet for the tank
-14>2x>18
Hope this helps!
You have to make them have their least common denominator to add or subtract, in this case 36.
Multiply 1/12 by 3, to get the denominator 36: 3/36.
Multiply 7/9 by 4, to get the denominator 36: 28/36.
Now add the numerators: 3+28=31, 31/36 is as simplified as possible so your answer is 31/36 :) I hope this helps :)
Answer:
3/4 or 9/12 make the denominators the same then just add
You could multiply 6 times 3 to get your answer. The answer would be 18
