Answer:
1206 square centimeters
Step-by-step explanation:
Hello, I can help you with that
a tin is a cylinder,a cylinder is formed by 2 circles anda 1 rectangle
let's remember
Area of the circle
Area of the rectangle
the length of the rectangle is the height of the tin (16 cm)
and the wide is equal to the perimeter of the circle
perimeter of the circle(P)
so, the area of the rectangle is
Step one
find the total area:
the total area is equal to 2 circles + 1 rectangle
Step two
put the values into the equation
height = 16 cm
radius= 8 cm
so, the total area is 1206.37 square centimeters
I hope it helps, have a great day.
ANSWER
where,
EXPLANATION
We want to simplify the rational expression
We can observe that the numerator of the given rational expression is a quadratic trinomial and the denominator is a difference of two squares
We need to split the middle term in the numerator and rewrite the denominator as a difference of two squares to obtain,
We now factor to obtain,
This implies that,
We now cancel out common factors to obtain,
The restriction is that, the denominator cannot be zero.
Thus
This implies that,
