Answer:

See below

Explanation:

Find the radius

circumference = pi d

16 pi = pi d

then d = 16 radius = 8 units

area of the TWO ends = TWO * pi (8)^2 =128 pi units^2

Find the height

hypotenuse = 10 one leg = radius = 8

10^2 = 8^2 + h^2

h = 6 units

lateral area = circumference * height

= 16 pi * 6 = 96 pi units^2

total area is then 128 pi + 96 pi = 224 pi units^2
