113 sq. ft. is the area of a 12 foot diameter circle.
Area of a circle = pi*r^2
Radius = r = d/2
In this question, d=12
So,
r = 6
Area of a circle = 6^2 *pi = 36*pi sq. ft
Circumferance = 2 X Pi X Radius (C = 2 X Pi X R) So R = C / (2 X Pi) Area = Pi X R2 So Area = Pi X (C / (2 X Pi))2 = 3.14 X (20 / (2 X 3.14))2 = 31.9 square foot
to answer this, use the formula, (pi)r^2. This gives you the answer 25(pi) or 78.54.
If the diameter is 18 feet then the area is about 254.469 ft².
If the radius is 18 feet then the area is about 1017.876 ft².
C = 11 so D = 11/pi, making R = 11/2pi. A = 121/4 pi2 x pi = 121/4 pi = 30.25/pi
= about 9.6 sq feet
452.39 square feet.

A circle with a diameter of 18 feet has an area of 254.5 square feet.
A circle with a diameter of 24 feet has an area of 452 square feet.
Area of the circle in square feet: pi*radius squared
452 square feet.
50.24 square feet
153.93804 square feet.
3.14159265 square feet.
That would be 5026.55 square feet.
