Bella is building two wigwams for a school project on american indian tribes. she first builds two wooden frames, each in the shape of a cone with a base radius of 2 feet and a slant height of 5 feet. if bella wants to cover the frames in fabric, how many square feet of fabric will she need? (use 3.14 for pi and round to the nearest whole number. recall the formulas l a = pi r l and s a = pi r l pi r squared.) square inches

The amount of fabric needed = 2(surface area of the cone-shaped wooden frame) = 88 ft².

What is the surface Area of a Cone?

Surface area of a cone = πr² + πrl

Given the following dimensions of the cone-shaped wooden frame:

  • Slant height (l) = 5 feet
  • Radius (r) = 2 feet

Amount of fabric needed = 2(surface area of the cone-shaped wooden frame) = 2(πr² + πrl)

= 2(3.14 × 2² + 3.14 × 2 × 5)

= 87.92

Amount of fabric needed ≈ 88 ft²
