Find the area of a circle 15 ft?
Area_circle = π × radius²It depends to what the 15 ft refers, if:15 ft is the radius of the circlearea = π × (15 ft)² = 225π sq ft ≈ 707 sq ft 15 ft is the diameter of the circlediameter = radius × 2 → radius = ½ diameter→ area = π × (15 ft / 2)² = 225π/4 sq ft ≈ 177 sq ft15 ft is the circumference of the circlecircumference = 2 × π × radius → radius = circumference ÷ (2π)→ area = π × (15 ft / 2π)² = 225/(4π) sq ft ≈ 17.9 sq ft
How many sq ft in 4 ft by 8 ft?
32 sq. ft.
What is the circumference of a circle with the radius of 4?
The circumference of a circle with a radius of four is: 25.13
If the radius of a circle is 2 inches what is the diameter?
its 4..... the radius of a circle is half of the diameter
What is the area of a circle with radius of 4cm?
A circle with a radius of 4 cm has an area of 50.27 square cm.
How sq ft in a 4 ft circle?
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.
What is the area in feet of a 12 inch circle?
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.

The radius of a circle is 2 feet what is the area of the circle in square feet?
4 x Pi, or about 12.5 square feet12.56637 sq. ft.
HOW MANY SQ FT IN A 21' CIRCLE?
441pi/4 sq ft
If the radius of a circle is 4 cm what is the area of the circle?
4 cm radius = Area of 50.26548 sq. cm.
What size is a 4ft round table?
I assume that you mean it's 4 ft in diameter, and you want to know the number of Sq Ft in the top. If so, the Area is equal to (Pi) X (Radius squared.) OR Since the Radius of a circle is 1/2 the Diameter ... the answer is [(4/2) X (4/2)] X Pi OR 4 X 3.14159 == 12.56636 Sq Ft
What is the circumference of a circle witha radius of 4 ft?
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
What would be the area of a circle with a width of 3ft?
I assume you mean a diameter of 3 feet. Divide the diameter by 2, to get the radius. Then use the standard equation for the area of a circle: area = π x radius^2 = π x (3 ft ÷ 2)^2 = 9/4 π sq ft ≈ 7.07 sq ft
What is the circumference of the circle if the radius is 4 ft?
It is 8*pi = 25.13 ft, approx.
What is the radius of a circle with a diameter of 8 ft?
16 ft. (d = 2r)
What is the area of a 14 foot circle?
Area of circle = Pi x diameter2/4 = 153.96 sq ft for a 14 ft circle
