If a circle is 3.4 miles around how many acres is it?

Answer 1

To find the area of a circle given its circumference, we can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is approximately 3.14159. Plugging in the given circumference of 3.4 miles, we get A = (3.4^2) / (4 * 3.14159) ≈ 0.909 acres. Therefore, a circle with a circumference of 3.4 miles has an area of approximately 0.909 acres.

Answer 2

Circumference = 2 pi R

R = (circumference) / (2 pi)

Area = pi R2 = pi ( C / 2pi )2 = C2 / 4pi

1 square mile = 640 acres

Acres = 640 x (3.4)2 / (4 pi) = 588.75 acres (rounded)

= approx. 0.92 square miles

Answer 3

To find the area of a circle given its circumference, we use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is a mathematical constant approximately equal to 3.14159. Plugging in the values, we get A = (3.4^2) / (4 * 3.14159), which is approximately 0.72 acres.

Answer 4

Area = pi R2 = (9 pi) square miles

Each square mile = 640 acres.

The circle = (9 x 640 x pi) = 18,095.6 acres (rounded)
