radius = diameter ÷ 2 area = π × radius² = π × (diameter ÷ 2)² = π × (141 ÷ 2)² = 4970¼ π sq ft ≈ 15614.5 sq ft
pi ft^2
(23-ft x 9-ft) x (1 meter / 3.28084 feet)2 = 19.231square meters (rounded)
Assuming that the questions refers to the AREA of a CIRCLE with an 11 foot diameter, the answer is pi*(11/2)2 = 95.033 sq ft (to 3 dp).
Assuming the diameter is 4 feet, then the radius is half. 4 / 2 = 2 ft.
If it is 1 foot diameter by 4 feet long, then it's pi*(1/2 ft)2 * (4 ft) = (pi) ft3. If it's 4 feet diameter by 1 foot tall, then it's pi*(2 ft)2 * (1 ft) = (4*pi) ft3.
radius = diameter ÷ 2 area = π × radius² = π × (diameter ÷ 2)² = π × (141 ÷ 2)² = 4970¼ π sq ft ≈ 15614.5 sq ft
26.24 ft 1 Meter = 3.28 ft 1 foot = 0.3048 m
pi ft^2
(23-ft x 9-ft) x (1 meter / 3.28084 feet)2 = 19.231square meters (rounded)
1.57 m 1 Meter = 3.28 ft 1 foot = 0.3048 m
You have answered the question for yourself!!! THe answer is 2 ft.
1 square foot (ft^2) = 0.0929 square meters (m^2)
Assuming that the questions refers to the AREA of a CIRCLE with an 11 foot diameter, the answer is pi*(11/2)2 = 95.033 sq ft (to 3 dp).
Assuming the diameter is 4 feet, then the radius is half. 4 / 2 = 2 ft.
11 ft diameter gives area = 95.03 sq feet (to 2 dp)
area = π x (diameter ÷ 2)2 = π x (26 ÷ 2)2 = 169π ~= 531 sq ft.
