Help Plz! Ellis is painting wooden fenceposts before putting them in his yard. They are each 7 feet tall and have a diameter of 1 foot. There are 11 fenceposts in all. How much paint will Ellis need to paint all the surfaces of the 11 fenceposts? Use 3.14 for π, and round your answer to the nearest hundredth. Provide an explanation and proof for your answer to receive full credit.

Ellis needs 259.17 square feet of paint.

Each fence post has a cylindrical format.

Ellis paints the outside of each post, which means that the surface area of each cylinder has to be found.

She paints 11 fence posts, so the total amount of paint needed is the surface area of the 11 fence posts.

Surface area of a cylinder:

The surface area of a cylinder of radius r and height h is given by:

7 feet tall, diameter of 1 feet:

7 feet tall means that

Diameter of 1 feet, radius is half the diameter, so

How much paint?

11 fence posts, so:

Ellis needs 259.17 square feet of paint.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
