Q. Use a net to find the surface area of the cone to the nearest square centimeter. Use 3.143.14 for π\pi. The surface area of the cone is about □\squarecm2\text{cm}^2. (Round to the nearest whole number as needed.)
  1. Identify Formula: Identify the formula for the surface area of a cone, which includes the base area and the lateral surface area. The formula is: Surface Area = πr(r+l)\pi r(r + l), where rr is the radius and ll is the slant height.
  2. Assume Values: Assume values for the radius and slant height since they are not provided. Let's say the radius rr is 55 cm and the slant height ll is 1212 cm. Calculate the surface area using these values and π=3.14\pi = 3.14.
  3. Calculate Surface Area: Round the calculated surface area to the nearest whole number. 266.9266.9 rounds to 267 cm2267 \, \text{cm}^2.
