Answer 1

Answer:

$B)~1011.08~ft^2$

Step-by-step explanation:

The total surface area of a cylinder is the sum of the areas of the bases and the lateral area. The bases are congruent circles. The lateral surface is a rectangle that has as dimensions the circumference of the base and the height of the cylinder.

The problem does not state what to use for pi, so I will use pi = 3.14.

$surface~ area~ of~ cylinder = 2 \pi r^2 + 2 \pi r h$

$SA_{cylinder} = 2 \pi r(r + h)$

$SA_{cylinder} = 2 (3.14)(7~ft)(7~ft + 16~ft)$

$SA_{cylinder} = (43.96~ft)(23~ft)$

$SA_{cylinder} = 1011.08~ft^2$

Answer 2

Answer:

B.  1,011.08

Step-by-step explanation:

The formula for surface are of a cylinder is

SA = 2πr² + 2πrh      where r is the radius of the base, and h is the height

We are given r = 7 and h = 16, plug those values in and evaluate

SA = 2π(7²) + 2π(7)(16)

 SA = 98π + 224π

    SA = 322π

**I'm assuming they are saying to use 3.14 as an approximation for π, so we have..

  SA = 322(3.14) = 1,011.08
