Find the surface area. round to the nearest hundredth when necessary.

We have the surface area of the cylinder as 3,016.32 in^2

Step-by-step explanation:

What we have here is a cylinder of height 14 inches and diameter 32 inches

Mathematically we can calculate the surface area of a cylinder using the formula;

A = 2 * pi * r(r + h)

where r is diameter/2 = 32/2 = 16 inches

h = 14 inches

pi = 3.142

thus, we have it that;

A = 2 * 3.142 * 16(16 + 14)

A = 3016.32 in^2

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
