Answer:
The formula to calculate the total surface area of a cylinder is expressed as, total surface area of cylinder = 2πr(r + h). This total surface area includes the area of the 2 bases (2πr2) and the curved surface area (2πrh). Here 'r' is the radius and 'h' is the height of the cylinder.
Step-by-step explanation:
Answer:
7x^2+21x+14
Step-by-step explanation:
With this all we have to do is foil:
first outside inside last
first: 7x^2
outside: 14x
inside: 7x
last: 14
we now combine them to
7x^2+14x+7x+14
we add like terms
7x^2+21x+14
