Estimate each product 7.1 x 2.1

14

Step-by-step explanation:

7.1 rounded is 7

2.1 rounded is 2

so the answer should be 14

1. the radius of the inscribed circle is   equal to 4 cm. since it is equal to the half of the length of the side of the square since the circle is tangent to one of the side of the square.
2. the radius of the circumscribed square is = to sqrt of 32 since by pythagorean theorem, the radius of the circumscribed circle is = the square of the sum of half of the side of the square ((4^2 + 4^2))^1/2
