100 sq. feet

Answers

  1. Answer:
    314 sq. feet
    Step-by-step explanation:
    The surface area of the pool would be the area in math. The equation for solving the area of a circle goes as follows:
    A=πr^2
    π·10^2

  2. Answer:
    A
    Step-by-step explanation:
    A circular shaped pool.
    The radius is 10 feet.
    We need to find the surface area to make a cover for the pool.
    We can use the formula for the area of a circle:
    A = \pir²
    A = (3.14)(10)(2)
    A = (31.4)(2)
    A = 62.8
    The minimum amount of material needed to make a cover is 62.8 square feet.
    hope this helps 🙂
