Area = pi*r2
r(radius) = diameter/2
15 feet/2
= 7.5 feet in radius
----------------------------So....,
Area = pi(7.5 ft)2
= 177 ft2
=======
Area = 176.71 feet2
The circle's area is 176.71 square feet.
Using 3.14 as Pi the area of circle is: 176.625
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
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.
diameter is 15 area of the circle is... 706.5 if im not mistaken
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
15 pi feet
The area is 176.714 units2
706.5cm
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 feet.
