The diameter of a circle is 38 miles. What is the circle’s area?

Use 3.14 for pi

Area of circle formula: πr^2

Since the radius is half of the diameter, divide 38 by two.

r = 19 miles

A = π(19)^2 = π(361)

Now, substitute in 3.14 for π

A = 3.14(361) = 1133.54

450

step-by-step explanation:

you get texts and minutes, so why not

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
