Can someone help write an equation for the circle?

x²+y²=9

Step-by-step explanation:

since it's on the origin its x²+y²

and you square the radius which is 3

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
