Mrs. amrien made a cylindrical pencil holder. it has a height of 5 in and a diameter of 3 in. how much material does she need to make her pencil holder

3 divided by 2 equils 1.5 that's the radius

Then pi x radius squared

Then times that by the length the answer is

35.34291735

Area of the side around = 3x5 = 15 inches²

the area of the bottom is π x radius² = π x 1.5² = 7.07inches

(the diameter is 3 therefore the radius is 1.5)

all of the material needed is the side and the bottom = 15+7.07 = 22.07inches
