### Estimate the area of each circle use 3 to approximate 4 feet?

You don't mention whether the 4 feet is the circumference, diameter or radius. The area of a circle is pi times the radius squared. If 4 feet is the circumference, the area is about 1.3 feet squared. If 4 feet is the diameter, the area is about 12.6 feet squared. If 4 feet is the radius, the area is about 50.3 feet squared.

### Estimate the area of each circle use 3 to approximate 4 feet solve it?

If 4 feet is the diameter, the area is about 12.6 feet squared. If 4 feet is the radius, the area is about 50.3 feet squared.

### What i square foot of a 4 ft radius?

Area of a circle with a 4 feet radius = 16*pi square feet

### Circle A has radius 4 feet circle B has radius 9 feet What is the ratio of the area of circle A to the area of circle B?

Area(A)/ Area(B) = pi*rA2/pi*rB2 = rA2/rB2 = 16/81

### How do you convert 4 ft x 4 ft to a circular diameter?

The 4' x 4' figure has an area of 4' x 4' = 16 square feet. The area of a circle is pi times the square of the radius. If a circle has an area of 16 square feet, then pi x r2 = 16 ft2. We'll take the 16, divide it by pi and the answer will be the square of the radius. And 16/pi = about 5.093 square feet and the square root of that is about 2.257 feet. The radius of a circle with an area of 16 ft2 is about 2.257 feet. The diameter of a circle is twice its radius, and in this case, 2.257 feet x 2 will have be the circle with a diameter = 4.514 feet.

### What is the area The diameter of a circle is 8 feet.?

The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 8 feet, the radius would be half of the diameter, which is 4 feet. Plugging this into the formula, the area of the circle is approximately 50.27 square feet.
