The diameter of a circle is 140 ft. What is the area of the circle.
The radius of the circle is half of the diameter, which is 70 ft.
The formula for the area of a circle is A = πr², where π (pi) is a constant value approximately equal to 3.14.
Substituting the radius, we get:
A = 3.14 x 70²
A = 3.14 x 4900
A = 15,386 square feet
Therefore, the area of the circle is 15,386 square feet.
