Answer:
It would be 16 probably
Step-by-step explanation:
Sorry if this is incorrect the question is kinda confusing
Answer:
Find the length of the diameter and the length of the circumference of the circle. Divide the length of the circumference by the length of the diameter. Set up an equation showing the ratio of the circumference to the diameter equal to π . Then rearrange the equation by solving it for the circumference. Substitute 2 times the radius for the diameter.
I got b I think that’s the answer
The answer would be 36.75 units squared because the area of the big square is 196 units squared, then take away (minus) the area of the smaller square, 49 units squared is 147 units squared, then simply divide it by four because the grey area represents a fourth of the space in between the squares so that brings you to 36.75 units squared.
