22 ft. The diameter is the measurement of a circle through the center from side to side and is equal to two times the radius.
36 feet across, 18 feet from centre to circumference, or 113.1 ft (approx) around the circle.
The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle. In this case, the radius is half of the diameter, so it would be 15 feet. Plugging this into the formula, we get C = 2π(15) = 30π feet. This is approximately 94.25 feet around a 30-foot circle.
if you have a square acre how many ft. across is it
If the diameter of the circle is 4 feet across the area is about 12.6 sq ft. You can check this by using the formula Area=Pi times the radius squared.
The circumference is 47.1 feet.
15 feet.
94.248 feet.
4 ft circle by 15 ft long, (4/2)2 x pi x 15 = 188.5 cu ft 188.5 x 35.315 = 6,656.658 litres
The circle's area is 176.71 square feet.
Assuming the 15 feet is the diameter of the circle. Formula to find the circumference of the circle is pi x diameter. 15 × 3.14 = 47.1 feet So the rope will be 47.1 feet long.
15 ft * 15 ft = 15*15 sq ft = 225 sq ft
