Togeher they have 9 + 6 = 15 apples.
To find the circumference of a circle you multiply pi (3.14) by the diameter ad to find the area you multiply pi (3.14) times the radius squared
Since the circumference is 31.4 divide that by pi to find the diameter which is 10
The radius of a circle is half of the diameter, so for this circle the radius is 10 / 2 = 5
Take the radius and square it : 5^2 = 25
Then multiply the squared radius by pi (3.14) to find the are : 25 * 3.14 = 78.5
So the area of this circle is 78.5 centimeters squared

Input is the value of x, output is the value of y
when the input is 2, that is, when x is 2, y=-4(2)²-8=-16-8=-24
the output is -24 when the input is 2
