The correct answer is B. 8<=l<=10. You can find this because we know the length is 2 feel more than the width, so when the length is provided, we can find the area. 8*6 is 48, which is the minimum area, and 10*8 is 80, which is the maximum area allowed.

Answer:

B) $747.7 \ yd^2$

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) = $\frac{14}{2} = 7\ yd$

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 = $2\pi r(h+r)$

Substituting the given values we get;

Surface area of cylinder = $2\pi \times 7(7+10)= 2\pi \times7\times 17 = 747.699 \yd^2$

Rounding to nearest tenth we get;

Surface area of cylinder = $747.7 \ yd^2$

Hence the surface Area of cylinder is $747.7 \ yd^2$ .
