I believe you are asking for how many Square Feet are in a 15 Foot Circle, So that's What I will answer below:
AREA of a CIRCLE = (pi) x radius2
*where pi = 3.14159 & radius is half the diameter
IF YOU ARE SAYING THE DIAMETER OF THE CIRCLE IS 15 FEET, THE ANSWER IS:
3.14159 x 7.52 = 176.714438 Sq. Feet
IF YOU ARE SAYING THE RADIUS OF THE CIRCLE IS 15 FEET, THEN THE ANSWER IS:
3.14159 x 152 = 706.85775 Sq. Feet
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.
The circumference is 47.1 feet.
Using 3.14 as Pi the area of circle is: 176.625
The circumference of a circle with a diameter of 3 feet is 9.4 feet.
Area of a circle = pi*radius squared
A 15-foot wide circle has an interior area of 176.71 square feet and a distance around the outside (circumference) of 47.1 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.
If the circle has a diameter (all the way across) of 15 feet,then its area is 176.7 square feet, rounded to one decimal place.
176.625
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.
assuming that 15 x 15 are the dimensions of the square that ensconces the circle in question. This means that the diameter of the circle is fifteen feet. Therefore the radius is 7.5'. area = pi x rr area = 3.14 * 7.5 *7.5 area = 176.715 m**2
If you mean a circle of diameter 135 feet, the area is Pi x 1352/4 = 14315.7 sq ft
Area of a circle is PI times the square of the radius (half the diameter). 3.1415 x (7.5 squared) = about 176.7 square feet
15 pi feet
The radius is 15 feet 2r=30 30/2=15 15 is the radius
It would be about 56.5 feet.
The circle's area is 176.71 square feet.
