area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2

The area of a circle can be calculated using the formula: A = πr^2. If the diameter is 21ft, the radius would be half of that, which is 10.5ft. The area of the circle would be approximately 346 square feet.

It is: 72*pi square feet if the radius is 12 feet and not12 square 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.

If a circle is 50 feet wide, that means its diameter is 50 feet. The radius of a circle is half the diameter, therefore the answer is 25 feet.

The area of a circle can be calculated using the formula: A = πr^2. If the diameter is 21ft, the radius would be half of that, which is 10.5ft. The area of the circle would be approximately 346 square feet.

Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2

It is: 72*pi square feet if the radius is 12 feet and not12 square feet

The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.

No, area of a circle is pi x radius x radius Radius is half the diameter. So the diameter of something giving 11.5 square feet as an area, must be much much smaller.

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.

The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)

4 feet. The radius is half the diameter.

The formula for the area of a circle is pi (3.141265...) times the radius squared. Since half of the diameter is the radius, plug that number into the formula to get the total square feet.

The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.

If a circle is 50 feet wide, that means its diameter is 50 feet. The radius of a circle is half the diameter, therefore the answer is 25 feet.
