Ezra measures the upper rim of a funnel and calculates that it has a circumference of 43.96 centimeters what is the rims radius
We know that the circumference of a circle is given by the formula C = 2πr, where r is the radius. So to find the radius of the funnel's upper rim, we can rearrange this formula to solve for r:
r = C/2π
Plugging in the given value for the circumference:
r = 43.96/2π
r ≈ 7.00
So the radius of the funnel's upper rim is approximately 7.00 centimeters.
To find the radius of the upper rim of a funnel, we can use the formula for the circumference of a circle:
Circumference = 2 * π * r
Given that the circumference is 43.96 centimeters, we can rearrange the formula to solve for the radius (r):
43.96 = 2 * π * r
Divide both sides of the equation by (2 * π):
r = 43.96 / (2 * π)
Using a calculator to compute this value, we get:
r ≈ 6.99 centimeters
Therefore, the radius of the upper rim of the funnel is approximately 6.99 centimeters.
