Answer:
B)
Step-by-step explanation:
Given:
Height of cylinder (h) = 10 yd
Diameter of cylinder (d) = 14 yd
We need to find the surface area of the cylinder.
Solution:
First we will find the radius of the cylinder.
Radius is half of the diameter.
radius (r) =
Now we know that;
Surface area of cylinder is equal to 2 times π times radius(r) times sum of radius (r) and height (h).
Framing in equation form we get;
Surface area of cylinder =
Substituting the given values we get;
Surface area of cylinder =
Rounding to nearest tenth we get;
Surface area of cylinder =
Hence the surface Area of cylinder is .
