Circ = 2 x pi x r = 20 so pi x r = 10 so r = 10/pi = 3.18, taking pi as 22/7
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the given measurement of 20 meters refers to the diameter, the circumference would be ( C = \pi \times 20 \approx 62.83 ) meters. If 20 meters is the radius, then the circumference would be ( C = 2\pi \times 20 \approx 125.66 ) meters. Please clarify whether 20 meters is the diameter or radius for a precise answer.
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.

pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
Circumference = 2*pi*r = 125.66 metres
The radius of this circle is 10 units.
The radius of a circle whose circumference is 40pi is 20 units.
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius.

If 20 meters is the radius, then the circumference would be ( C = 2\pi \times 20 \approx 125.66 ) meters. Please clarify whether 20 meters is the diameter or radius for a precise answer.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
To find the radius of a circle with a circumference of 20 inches, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 20 inches, you can plug this value into the formula: 20 = 2πr. Solving for r, you get r = 20 / (2π) ≈ 3.183 inches. Therefore, the radius of the circle is approximately 3.183 inches.
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 20, the circumference would be C = 2 * 3.14159 * 20 = 125.6636 units.

pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
radius = 20/(2*pi) = 3.183098862 inches
