Find the circumference of a circle with radius of 18 in. leave your answer in terms of pi

We get the circumference of a circle by multiplying 2 times pi times the radius (r).

C= 2πr

We punch this into a calculator:

2π(18)

and we get

113.097335529

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
