Question

What is the formula for finding the area of a circle

Answer 1

\(A = \pi r^2\)

Answer 2

What about circumference?

Answer 3

What's r? & ?

Answer 4

I think r is radius
Half the distance of circle

Answer 5

\(C = d \pi\)

Where d = diameter.

Answer 6

Or

\(C = 2r \pi\)

Answer 7

Where r = radius.

Hint: (2 times the Radius = Diameter)

Answer 8

My question is saying that the diameter is 6 what is the area. FIND THE EXACT ANSWER

Answer 9

\(A = \pi r^2\)

The diameter is HALF the radius.

Half of 6 is 3.

\(A = (\pi) (3^2)\)

\(A = (3.14)(9)\)

\(A = 28.26\)

Answer 10

So you make the diameter a radius then multiply that to the 2nd power then multiply by pi?????
