Question

Find the circumference of the circle that has a radius measurement of 11 1/4

Answer 1

70.69 or 22.5 pi

Explanation:

To find the circumference of a circle, you can use the formula:

2 x pi x radius

Using this formula, we can substitute the information that we already know, and solve for the circumference:

2 x pi x 45/4

6.28 x 45/4

70.69 or 22.5 pi

Answer 2

22.5π units² or about 70.65 units²

Explanation:

11
`(1)/(4)` is equivalent to 11.25

The formula for the circumference of a circle is 2πr. Using that formula we get:

2*π*11.25 = 22.5π ≈ 70.65
