What is the area of this circle.
15 in
??

So the formula for the area or a circle is πr². You however have been given the diameter, (line all the way across the circle) so to work out the radius we would divide 15in by 2 which gives us 7.5. Now we know the radius, it’s just a process of substitution. π x 7.5² = 176.7145867644259. But we need to get this answer in π form. So we divide 176.7145867644259 by π = 56.25π

Answer = 56.25π

15

Step-by-step explanation:

The answer is 1/4

Step-by-step explanation:

It's 1/4 because it's the least amount and it has x's above it.
