What is the diameter if the circumference of a circle is 40cm?
D = ~12.73 cm
What is the circumference of a circle if the diameter is 40cm?
The circumference (C) of a circle is given by the formula C = 2πr But, the diameter equals twice the radius so we can write C = πd....where d is the diameter. So, C = 40π = 125.664 (3dp)
How do you find the circumference of a circle if the diamter is 40cm?
circumference = pi*40cm
What is the radius if the dianeter is 40cm?
The Diameter is the distance from one side of the circle all the way to the other side. The Radius is half the distance in a circle. Simply put: 40cm = Diameter 20cm = Radius (Half the distance) :)
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.

How many revolutions are made by a wheel 40cm in diameter in travelling 352m?
Diameter = 40 cm implies circumference = 40*pi = 125.7 cm So, in travelling 352 metres = 35200 cm, the wheel will rotate 35200/125.7 = 280.1 times (approx).
What is the area of a circle whose radius is 40cm?
A = 5026.5 cm2
What is the area of a circle with a radius of 40cm?
A circle with a radius of 40 cm has an area of 5,026.55 square cm.
What would be the radius if the circumfernce is 40cm?
The radius of a circle can be found using the formula for the circumference, which is ( C = 2\pi r ). If the circumference is 40 cm, we can rearrange the formula to solve for the radius ( r ): [ r = \frac{C}{2\pi} = \frac{40}{2\pi} \approx \frac{40}{6.28} \approx 6.37 \text{ cm}. ] Thus, the radius is approximately 6.37 cm.
