Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by = 
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder

area of base is give by 
since there is only one base area of that base
= 
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
3.14*d
3.14*12= 37.68
Rounded to the nearest hundredth would be 37.7
Answer:
4.56
Step-by-step explanation:
After this equation is simplified, it is solved the way any 1-step linear equation is solved.
__
1.4t -0.4(t -3.1) = 5.8 . . . . . . given
1.4t -0.4t +1.24 = 5.8 . . . . . eliminate parentheses
t +1.24 = 5.8 . . . . . . . . . collect terms (now you have a 1-step equation)
t = 4.56 . . . . . . . . . .subtract 1.24
Answer:

Here,
denotes the required number.
Step-by-step explanation:
Let
denotes the required number that satisfies the following condition.
''seven times a number is less than or equal to a quantity that is 24 less than that same number''
Seven times a number is equal to 
Quantity that is 24 less than that same number is equal to 
Now find the inequality.
As seven times a number is less than or equal to a quantity that is 24 less than that same number,
