The answer depends upon how many decimal places you will assign to pi. Assuming 3.14159 is good enough for your use, the answer would be 18.84954. If your calculations are more critical, you may want to use calculate your answer by assigning more decimal places to pi; pi calculated to 50 decimal places is 3.14159265358979323846264338327950288419716939937510. My calculator will only accept 15 decimal places; in that case pi is 3.141592653589793, multiply that by 6, and the answer is now 18.849555921538758.

What is the area of a circle if it is 12ft?
Assuming the 12ft is the diameter of the circle. The formula is A = pi x r2 Pi = 3.14 for general use. Therefore, (6 x 6) x 3.14 = 113.04ft2
How do you find the circumference and area of a circle from the radius?
The circumference C is pi times the diameter of the circle, which is twice the radiusC= pi *2rThe area A is pi times the radius squaredA = pi r2where pi = about 3.14159Example:For a radius of a 3 cmC = pi x (3 x 2) = pi x 6 = about 18.85 cmA = pi x (3)2 = pi x 9 = about 28.275 cm2
What is the radius of a circle whose circumference is 37.68?
Circumference_of_circle = 2 x {pi} x radius radius = circumference / (2 x {pi}) ~= 37.68 / (2 x 3.14) = 6
What is the area and circumference of a 12 yd diameter circle?
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.
What is the integral from 0 to pi over 6 sine 2x dx?
Integral from 0 to pi 6sin2xdx: integral of 6sin2xdx (-3)cos2x+c. (-3)cos(2 x pi) - (-3)cos(2 x 0) -3 - -3 0
Area of a circle with the diameter of 12feet?
A = pi x r x r So: A = pi x 6 x 6, or 36 x pi = 113.097 square feet.
How do you find the general solutions of csc x equals -2?
Cosec x = -2 => sin x = -0.5 The primary solution is x = -pi/6 radians. Therefore the solutions are: 2n*pi - pi/6 and (2n+1)*pi + pi/6 for all integer n.
What is pi x 6 ft?
pi*6 = 18.84955592 feet or about 19 feet
A circular garden has a radius of 6 ft What is the area of the garden in terms of Pi?
Are is found by (pi)r^2 or pi times the "radius squared" in this case it is (pi) x 6 squared = (pi) 36 Your answer 36 (pi) squared feet As mentioned above, the formula is A = Pi x R² where Pi = 3.1416 and R² is the radius multiplied by itself. Now, to apply the formula: A = 3.1416 x (6 x 6) = 3.1416 x 36 = 113.0976 sq ft.
What the circumference of a circle if the diameter is 6?
circumfrance= pi x diameterc= pi x 6c= 18.85
What is 6 x pi to the power 5?
mass of proton is 6 x pi raised to power 5 times mass of electron
What is the circumference with a radius of 6?
The formula for working out the circumference is 2pi x radius, aka pi diameter. The radius is 6 so times this by 2 and then pi. The answer would be: (6 x 2) x pi = 12 x pi = 37.69911184. Pay attention in maths lessons next time! ;) Hope this helps.
When is the equation cotangent of x plus the square root of 3 equals 0 in the interval of 0 to 3pie?
First of all, it is pi, a letter of the Greek alphabet, not pie! cot(x) + sqrt(3) = 0 cot(x) = -sqrt(3) tan(x) = -1/sqrt(3) The principal value is x = -pi/6c. So the solutions are (-pi/6 + k*pi) radians where k is an integer: that is k = 1 => 5*pi/6 k = 2 => 11*pi/6 k = 3 => 17*pi/6
What is the area of a circle whose diameter is 6 feet?
diameter = 2 Pi R = 6 ft so R=diameter/(2 pi) area = Pi R² = Pi x diameter²/(2² pi²)=6²/(4 pi)
What is the circumference of the circle 6 in lenght of pi?
If you know the diameter, simply multiply diameter x pi.If you know the radius, multiply radius x 2 x pi.
What is the area of a circle if it is 12ft?
Assuming the 12ft is the diameter of the circle. The formula is A = pi x r2 Pi = 3.14 for general use. Therefore, (6 x 6) x 3.14 = 113.04ft2
What is the volume of a sphere with a diameter of 8 mm?
D = 8mm = Pi/6 x D3 = Pi/6 x 512 = 268.1 cubic millimetres (rounded).
