Circumference not required, and in any case doesn't make sense for a radius of 11; it should be 69.
A = pi x r x r = 121 pi = 380.12

What is the radius of a circle with a circumference of 69 centimeters?
Radius = circumference/2pi, in this case 69/2pi or 34.5/3.14, as near 11 cm as makes no difference.
What is the estimate circumference of a circle that has a radius of 11 m?
Circumference = 2 x pi x radius. If you want an estimate, you can round some of the numbers involved - either the radius, or pi, or both.
What is the circumference with the radius of 11 inches?
circumference = 2*pi*11 = 69.115 inches to 3 dp
What is the radius of a circle with an area of 11 in?
Area = pi*radius squared 11 in = pi*r^2 divide both sides by pi 3.50 in = r^2 take square root of each side 1.9 inches = radius
What is the surface area of a cylinder whose end area is 11 and height is 11 rounded to the nearest whole number?
Imagine taking the ends off the cylinder, cutting the side down from end to end and unrolling the side; this creates a rectangle with the height of the cylinder along one edge and the circumference of the end along the other. Thus area of side = circumference × height. The ends of the cylinder are circles, thus: area = π × radius² → radius = √(area ÷ π) circumference = 2 × π × radius → circumference = 2 × π × √(area ÷ π) = 2 × √(area × π) → area side = 2 × √(area × π) × height → surface area of cylinder = 2 × area ends + area side → surface area = 2 × 11 units² + 2 × √(11 units² × π) × 11 units → surface area = 22 + 22 × √(11π) units² → surface area ≈ 22 + 129.33 units² ≈ 151 units²

What is the circumference of a circle with a radius of 11?
The circumference of a circle with a radius of 11 is about 69.12The general formula is circumference = (2 x radius) x pi. Therefore, in this instance, the answer is 2 x 11 x pi = about 69.12.
What is the circumference of a circle when its area is 121 pie inches cubed?
the area can not be cubed. the area is always squared. volume is cubed. the formula for area is pie multiplied by radius squared. your formula for your circle is... A = 121pi in2 the radius in your circle is 11 inches the formula for circumference is two times pi times the radius C = 2 * (3.14159) * 11 your answer is 69.11498in
Circumference and area of a circle if the diameter is 11?
Radius, r = diameter / 2 Then circumference = 2*pi*r and area = pi*r*r
What is the circumference with a circle with a 11 inch radius?
Circumference = 2*pi*11 inches
What is the circumference of a circle with a radius of 11 cm?
The circumference of a circle with a radius of 11 is about 69.12 centimeters.The general formula is circumference = (2 x radius) x pi. Therefore, in this instance, the answer is 2 x 11 x pi = about 69.12
