What is the radius of a circle with a circumference of 35 cm?
radius = 35/(2*pi) in cm
What is the circumference of a 35 ft diameter circle?
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 35 feet, so the circumference would be C = π(35) = 110.19 feet.

What is the square foot of a 21 foot round pool?
If 21 feet is the diameter, divide it by 2 to get the radius. Then use the formula for a circle: area = pi x radius2. 350 sq ft NOT the 35 the other people answered. A sheet of plywood 4' by 8' is 32 Sq ft thats a really small pool.
How many radians is a dog that has been tethered with a 20 foot lead if the length of the path is 45 feet?
Oh, dude, let me break it down for you. So, if the dog is tethered with a 20-foot lead and the path it walks is 45 feet, that's like a radian situation. The angle in radians would be like 45 feet divided by the radius of the circle, which is 20 feet, so it's around 2.25 radians. But hey, who's counting, right?
