Answer:
125.6 sq ft.
Step-by-step explanation:
To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:
------------------------------
Area of bases: ()
Since we have two bases, we can simply multiply by 2, giving us:
12.56×2= 25.12
-------------------------------
Area of the rectangle: ()
12.56×8= 100.48
Add these two together, giving us:
100.48+25.12= 125.6 sq ft.
Given:
Sum of ages of brother and sister = 15
Product of their ages = 54
To find:
How old is the older one between the two of them?
Solution:
Let x be the age of brother and y be the age of sister.
Sum of ages of brother and sister = 15
...(i)
Product of their ages = 54
[Using (i)]
Splitting the middle term, we get
Using zero product property, we get
If , then using (i), we get
If , then using (i), we get
Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.
