Final answer:
The approximate area of a circle with a radius of 10 feet is 314 square feet. Therefore, the correct answer is A) 314 square feet.
Step-by-step explanation:
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. In this case, the radius is given as 10 feet. Substituting this value into the formula, we get:
A = π314.15927... square feet
Since the question asks for the approximate area, we can round the calculated value to two significant figures:
A ≈ 314 square feet
The approximate area of a circle with a radius of 10 feet is calculated using the formula A = πr², where π (pi) is approximately 3.1415927, and r is the radius of the circle. Plugging the radius of 10 feet into the formula gives us:
A = π(10 feet)² = 3.1415927 × 100 square feet ≈ 314 square feet. T
Therefore, the correct answer is A) 314 square feet.
