Answer:
28.3 square inches
Step-by-step explanation:
In the question, we are asked to calculate the portion of the area of the cake eaten by Ellie’s sister.
To calculate this, the first thing to do is to calculate the area of the cookie cake. Now, since it’s a round cake, then it must be circular in shape.
Hence we calculate the area.
mathematically the area of a circle can be calculated using the formula;
A = pi * r^2
here our r =6 inches
Substituting this, we have
A = 22/7 * 6 * 6 = approximately 113 sq. inches
we now move on to calculate the portion ate, which is a quarter
That would be 1/4 * 113 = 28.3 sq. inches was eaten
