Melinda is decorating for her sister's birthday party. She is making a conical tent that will have a slant height of 9 feet and a radius of 6.5 feet. Approximately how much fabric will she need to cover the surface of the entire tent? Use 3.14 for pi, and round your answer to the nearest hundredth. Melinda will need ft2 of fabric.

Answer:

Total surface area of cone = 316.355 ft²

Step-by-step explanation:

Given:

Slant height of cone (l) = 9 feet

Radius of cone (r) =  6.5 feet

Find:

Total surface area of cone.

Computation:

Total surface area of cone = πr(l+r)

Total surface area of cone = (3.14)(6.5)(9+6.5)

Total surface area of cone = (3.14)(6.5)(15.5

Total surface area of cone = 316.355 ft²
