Circumference = 2*pi*r = 125.66 metres
The radius of a circle whose circumference is 40pi is 20 units.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
If the circumference is 20 the radius is 3.18
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)
Circumference is 2 x pi x r = 3.14 x 2 x 20 = 3.14 x 40 ='125.6 cms
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 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.
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
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
