Answer 1

@Vocaloid

Answer 2

first calculate radius = (1/2) * diameter

then calculate area = pi * r^2 using 3.14 as pi

Answer 3

Whats the diameter?

Answer 4

it's in the problem

Answer 5

Also how would I set that up? XD

Answer 6

you are given the diameter

plug that into radius = (1/2)*diameter to find the radius

then calculate the area

Answer 7

(1/2) * d * r^2?

Answer 8

radius = (1/2) * diameter = ?

Answer 9

So I just write diameter?

Answer 10

No symbol representing it?

Answer 11

you are given the diameter value in the problem

take that number and plug that into the equation radius = (1/2) * diameter

Answer 12

Ohhhhh, sorry, took me a while and I had to go look back up and see what the diameter was.

Answer 13

Answer 14

good, then that's the radius

now find area = pi * r^2 = your answer

Answer 15

113.04. Sorry, you're probably tired of dealing with stupid me

Answer 16

it's fine

that's correct

Answer 17

I'll try on my own more
