circumference = 9.3*pi yards
Diameter = 2 x radius Area_circle = π x radius2 → radius = √(area_circle ÷ π) → diameter = 2 x √(area_circle ÷ π) 1 yd = 3 ft 1 acre = 4840 sq yds → diameter = 2 x √(4840 sq yds ÷ π) ≈ 78.501 yds ≈ 235.503 ft Area of one acre is 43560 square feet. Diameter of circle with an area of 43560 square feet = 235.503 feet diameter. An acre was the area an ox could plough in one day; it was described by a furlong long (220 yds) by a chain (22 yds) wide, giving an area of 4840 sq yds, though it can be any shape. (A furlong is an abbreviation of "furrow long" which is the length of one furrow, standardised to 220 yards.)
Because it has a radius, I'm assuming the area is a circle. The formula of area for a circle is A = pi*r2, so in this case the area is about 154 square yards.
2 yds 2 ft + 1 yds 2 ft = 3 yds + 4 ft = 3 yds + (1 yd 1 ft) = 4 yds 1 ft
how many ft is 11 yds
5 x 3 ie 15 sq yds
11.5 times pi yds
Circumference = diameter x Pi C=100 x 3.14 C=314yrds
Circumference = pi times D = 3.6 pi = 11.30973 yds (rounded) = approx. 11yds 11.15in
To measure the concrete needed for a circular pad:-- Decide how thick (deep) the pad is to be. If it's in inches, divide by 12 for thickness in feet.-- Measure either the circumference or the diameter of the circle, in feet.-- If you measured the circumference, then the cubic yds of concrete needed is(0.00295) x (circumference) x (circumference, again) x (thickness) ... all in feet-- If you measured the diameter, then the cubic yds of concrete needed is(0.0291) x (diameter) x (diameter, again) x (thickness) ... all in feet
(Note: for typing purposes, pi will be represented as n) The formula for circumference is 2nr. First we need to find 'r' which stands for radius (the straight distance from the centre of the circle to the edge). Since the radius is half of the diameter, the radius is 70/2=35 yds. Now we can put 35 yds into the formula: 2*n*35 = 219.91 yds (rounded to 2 decimal places).
Formula for finding circumference is Pi (3.14) X diameter, so 12 yds times 3.14 = yds. Formula for area is Pi (3.14) x radius (1/2 the diameter=6) squared. So the radius squared is 6 X 6 = 36, X 3.14. You can do the math! Area will be in square yds.
circumference of a circle = 2 * radius * pi= 2 * 3.5 * 3.14159= 21.99113 yds
The radius a circle with area of π*121 yd2 is 11 yds [= sqrt(121)] The circumference, therefore, is 2*11*π = 22*π yards.
50.2656 square inches The formula to find the area of a circle is ∏r2. Where ∏ is the mathematical constant and r is the radius of the circle. So 3.14 x 42. = 50.27 square cm or yds, (whatever the diameter was in).
Area = π × radius² → radius = √(Area / π) Circumference = 2 × π × radius = 2 × π × √(Area / π) = 2 × √(Area × π) 1 acre = 4840 sq yds → circumference = 2 × √(1.5 × 4840 sq yds × π) ≈ 302 yds.
Diameter = 2 x radius Area_circle = π x radius2 → radius = √(area_circle ÷ π) → diameter = 2 x √(area_circle ÷ π) 1 yd = 3 ft 1 acre = 4840 sq yds → diameter = 2 x √(4840 sq yds ÷ π) ≈ 78.501 yds ≈ 235.503 ft Area of one acre is 43560 square feet. Diameter of circle with an area of 43560 square feet = 235.503 feet diameter. An acre was the area an ox could plough in one day; it was described by a furlong long (220 yds) by a chain (22 yds) wide, giving an area of 4840 sq yds, though it can be any shape. (A furlong is an abbreviation of "furrow long" which is the length of one furrow, standardised to 220 yards.)
Circumference (C) is the distance around the circle and you want to know what the area(A) of the circle is? First you must find the diameter (D) of the circle, then the radius (R), and finally calculate A. {1} If C = Pi X D, then C/Pi = D, hence 3081 / 3.1416 = 98.071046. {2} D/2 = R, hence 98.071046 / 2 = 49.035523 {3} A = Pi X R-squared; hence, 49.035523 X 49.035523 = 2404.4825 X 3.1416 = 7553.9222 sq yds.
