A=πr², and r=d/2, so r=40 inches and A = 1600π sq in = 5026.55 sq in
The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is given as 80 inches. Plugging this value into the formula, we get C = π(80) = 251.327 inches. Therefore, the circumference of the circle with a diameter of 80 inches is approximately 251.327 inches.
A ≈ 5026.55cm2
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
80 inches (d = r x 2)
Area of a circle in square feet = pi*radius2
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
If the radius of a circle is 80 inches, then the area of the circle is 139.6263 square feet. (rounded)
What is a "160ft circle" ? Is that the circle's diameter ? Radius ?If the circle's diameter is 160ft, then its area is (pi) R2 = (pi) (80)2 = 20,106.2 square feet. (rounded)
Area = pi*402 = 5026.548 square cm to 3 dp
Diameter = 80/pi feet
If the diameter is 80 ft then the area is 5026.54 sq ft
