A cylinder has a height of 7 m and radius of 9 m. What is the surface area of the cylinder? Use 3.14 for pi and provide your ans
1 answer:
<h2>The surface area of cylinder is 904.32 square meter</h2>
<em><u>Solution:</u></em>
<em><u>The surface area of cylinder is given as:</u></em>
Where,
h is the height
r is the radius
From given,
h = 7 m
r = 9 m
<em><u>Substituting the values, we get,</u></em>
Thus surface area of cylinder is 904.32 square meter

First, we have to convert our function (of x) into a function of y (we revolve the curve around the y-axis). So:
And the derivative of x:
Now, we can calculate the area of the surface:
We could calculate this integral (not very hard, but long), or use (1), (2) and (3) to get:
Calculate indefinite integral:
And the area:
