PLZ HELP ASAP SOLID GEOMETRY WORD PROBLEMS

Answer 1

Area of a cylinder is computed by the formula: A=2πrh+2πr^2

So the solution will be:
A=2π(2)(5)+2π(2)^2
A=2(3.14)(2)(5)+2(3.14)(2)^2
A=87.96

SO the answer would be 84.96 square units.

Answer 2

Surface Area of a cylinder can be calculated as:

Surface Area = 2πr(r+h)

Values of r and h are given.
Radius = r = 2
Height = h = 5
π = 3.14

Using the values, we get:

Surface Area = 2(3.14)(2)(5+2)=87.92 square units

Thus the answer to this question is 87.92
